Te superčvorove moguće je generirati (nalogom SPENG), izostavljati (nalogom SPEDEL), rotirati (nalogom SPEROT) i izlistati (nalogom SPELIST), a ti se nalozi s objašnjenjima nalaze u meniju SUPERELEMENATA u MODSTAR-u.
Those supernodes can be generated (with the command SPENG), omitted (with the command SPEDEL), rotated (with the command SPEROT) and listed (with the command SPELIST), and these commands with explanations are found in the menu of SUPERELEMENTS in MODSTAR.

1, 2, 3, 4 and main), which are gradually calculated in that order.
[Tue Dec 23 10:09:31 2003]
Nakon provedenog proračuna za main konstrukciju, poziva se svaki od prethodnih problema s NEWPROB nalogom citirajući prethodni problem, pa se za svaki od njih provede analiza nalogom RUN_STATIC, RUN_STRESS, pregleda rezultat EDIT nalogom, i pregleda deformacije i napone RUN_static nalogom, za svaki superelement
After the calculation for the main structure has been carried out, each of the previous problems is called with the NEWPROB command, quoting the previous problem, and the analysis is conducted for each of them with the command,RUN_STATIC, RUN_STRESS, results are checked with the EDIT command, deformations and tensions are checked with the RUN_static command, for every superelement

Time se pokazalo kako i veći problem koji je inače nerješiv možemo riješiti pomoću ograničene (limited) verzije COSMOS/M-a
This showed that extensive problems which are usually unsolvable can be solved with the limited version of COSMOS/M

Problemi substrukturiranja se mogu rješavati u limitiranoj verziji GEOSTAR-a, kreiranjem zasebnih substruktura, te zatim za svaku kreiranu substrukturu treba kreirati ime(i).MOD datoteku (i=1,2,.
Problems of substructuring can be solved in the limited version of GEOSTAR, by creating separate substructures, and then, for each created substructure, name(i).MOD file (i=1,2,.

Zatim treba izaći iz GEOSTAR-a EXIT nalogom.
Then we should exit GEOSTAR, with the EXIT command.

Otvoriti MODSTAR pozivom iz COSWORK direktorija (upisati naloge SUBSTR i SPELE pozivom iz glavnog menija MODSTAR-a (SPECIAL TOPICS, ako ti nalozi prethodno nisu kreirani editorom), te provesti RUN_STATIC analizu s F10 izaći iz MODSTAR-a, ući u GEOSTAR, kreirati drugu substrukturu, kreirati ime2.MOD itd
Open MODSTAR by calling it from COSWORK directory, (enter the commands SUBSTR and SPELE by calling it from the main menu of MODSTAR - SPECIAL TOPICS, if these commands were not previously created with the editor), and carry out RUN_STATIC analysis, with F10 exit MODSTAR, enter GEOSTAR, create another substructure, create name2.MOD etc.

Treba još navesti, da se prilikom rješavanja problema substrukturiranja na disku pohranjuju svi podaci i sve matrice o svim substrukturama i o glavnoj konstrukciji
It should be noted that, that during solving substructuring problems, all data and all matrices about all substructures and the main structure are stored on the disk

Substrukturiranje građevinskih konstrukcija nije uobičajena tehnologija analiza konstrukcija.
Substructuring of building structures is not the usual technique of structure analysis.
[Tue Dec 23 11:06:25 2003]
Odavno postoji običaj da se odijele nad-konstrukcije (ma što to značilo) od podkonstrukcije (temeljne konstrukcije).
A long time ago, there was a custom to separate superstructures (whatever that meant) from substructures (basic structures).
[Tue Dec 23 11:08:26 2003]
Zatim se uobičajilo posebno razmatrati tlo, a posebno temeljnu konstrukciju.
Then it became a custom to analyze ground separately, and basic structure separately.
[Tue Dec 23 11:09:03 2003]
Naravno da je to bilo potrebno u predkompjutorskoj eri, kad nije bilo alata kojim bi se cjelokupni problem mogao rješavati u jednoj jedinoj analizi.
Naturally, this was necessary in the precomputer era, when there were no tools that could solve the entire problem in only one analysis.
[Tue Dec 23 11:12:21 2003]
Danas se konstrukcije, temelji i tlo smatraju jedinstvenim entitetima cjelovite konstrukcije.
Today, structure, foundations and ground are considered unique entities of the integral structure.
[Tue Dec 23 11:21:39 2003]
U drvenim konstrukcijama uobičajilo se razmatrati posebno glavnu konstrukciju (obično kao ravninski entitet), potom zasebno podrožnice, te vjetrovne i stabilizacijske vezove, a posebno temelje u odnosu na rezultate geomehaničkih ispitivanja.
In wooden structures, it became usual to analyze the main structure separately (usually as a planar entity), then purlins separately, as well as wind and stability binders, and foundations separately in relation to the results of geomechanical testing.
[Tue Dec 23 11:21:39 2003]
Iako su svi ti dijelovi jedinstveno uvezani u nosivu konstrukciju tek se u novije vrijeme prikazuje i razmatra 3D modele drvenih konstrukcija
Although all these parts are uniquely tied in a load carrying structure, only recently 3D models of wooden structures have been showed and analyzed

Promišljanja o znanju i mudrosti u kontekstu partnerskog dijaloga prirodnih znanosti i teologije
Reflections on knowledge and wisdom in the context of a partnership dialogue between natural sciences and theology
[Tue Dec 23 11:38:22 2003]
Partnerski dijalog prirodnih znanosti i teologije bi trebao povesti računa o činjenici da se suvremena znanstveno-tehnička civilizacija oslanja na pretpostavci stopljenosti prirodnih znanosti s tehnikom.
Partnership dialogue between natural sciences and theology should take into account the fact that contemporary scientific-technical civilization lies on the assumption of natural sciences being merged with technology.
[Tue Dec 23 11:38:59 2003]
Ta činjenica je odigrala, a još uvijek igra presudnu ulogu u poimanju ljudskoga znanja, kao i kvantitativnom uvećavanju i vrednovanju tih znanja.
That fact has played, and it still plays a crucial role in the comprehension of human knowledge, as well as the quantitative expansion and valuation of that knowledge.
[Tue Dec 23 11:40:11 2003]
Odvijanje i način života suvremenoga čovjeka je gotovo nezamisliv bez tih znanja.
Modern man's way and progress of life is almost inconceivable without these knowledges.
[Tue Dec 23 11:41:53 2003]
No, problem nije znanje kao takvo, već isključivo vrednovanje znanja u skladu s kriterijima znanstveno-tehničke učinkovitosti i koristi.
But, knowledge as such is not the problem, the problem is only the evaluation of knowledge according to the criteria of scientific-technical efficiency and benefit.
[Tue Dec 23 11:41:53 2003]
U takvim se uvjetima posve izgubio smisao za mudrost i usmjerenost znanja k mudrosti i iskustvu koji se ne mogu podvrgnuti mjernim kriterijima znanstveno-tehničke učinkovitosti i koristi
In such circumstances, the sense of wisdom has been lost completely, as well as the inclination of knowledge toward wisdom and experience which cannot be submitted to measuring criteria of scientific-technical efficiency and benefit
[Tue Dec 23 11:47:09 2003]
Logično je da znanstveno-tehnička civilizacija brižljivo vrednuje znanje postignuto u okvirima znanstvene i tehničke djelatnosti.
It is logical that scientific-technical civilization carefully evaluates knowledge achieved within scientific and technical activities.
[Tue Dec 23 11:47:43 2003]
Međutim, nije normalno stanje kad se prešutno podržava zaborav mudrosti, tj. zaborav znanja i iskustava koji svoj izvor imaju u religiji, vjeri i iskustvu transcendencije.
However, it is not normal when forgetting of wisdom is tacitly supported, that is, forgetting knowledge and experience that have their source have in religion, faith and transcendental experience.
[Tue Dec 23 11:49:01 2003]
Danas ima puno znanja, ali očito nedostaje mudrosti.
There is plenty of knowledge today, but obviously not enough wisdom.
[Tue Dec 23 11:49:49 2003]
Čovjek je zatrpan znanjima i informacijama koji se sve više fragmentiraju.
The man is showered with knowledges and information that become more and more fragmented.
