Danas postoji niz programskih paketa i programskih sustava kojima se može pomoću CAD-a kreirati model kojeg istražujemo, a zatim se ti modeli mogu predočiti konačnim elementima, koristeći razne automatske rutine za kreiranje mreža konačnih elemenata.
Today, there are series of software packages and systems which can be used, together with CAD, to create the model which we are exploring, and then these models can be presented with finite elements, using various automatic routines for creating finite element meshes.

U GEOSTAR modulu vremenski korak može biti izvanredno malen, pa se onda mora voditi strogi račun o izboru tipa rezultata analize, totalnom vremenu analize i vremenskom inkrementu pohrane proračunskih rezultata, neovisno o inkrementu vremenskog koraka analize, a ovisno o medijima pohrane (tvrdi disk s ograničenjem pohrane podataka) i sličnim pitanjima pohrane mnoštva podataka
In GEOSTAR module time step may be exceptionally small, and then one must be particularly careful about the selection of the type of analysis results, total analysis time and the time increment of storing calculated results, independent of the increment of analysis time step, and depending upon the media of storage (hard disk with the limitation of data storage), and similar matters of storing a large amount of data

Kod umrežavanja površina geometrije GLULAM nosača koriste se SHELL4L uslojeni KE sa 6 sloboda i s jednim slojem debljine širine nosača, jer se kod tih KE mogu zadati moduli EX, EY, GXY, kao i kut nagiba vlakanaca drveta u odnosu na lokalni koordinatni sustav
When meshing areas of GLULAM structure geometry, we use SHELL4L layered FEs with 6 freedoms and with one layer that is as thick as the girder is wide, because with these FEs modules EX, EY, GXY can be set, as well as the angle of inclination of wood fibers in respect to the local coordinate system

Podrožnice su s jedne strane oslonjene te se ne mogu dobiti realni podaci o progibu sprega za stabilizaciju nosača.
Purlins are supported on one side, so it is not possible to obtain real data about deflection of the binder for girder stabilization.
