I’m trying to use an orthotropic material definition in the .inp file.
The model runs fine in CalculiX and is analyzed successfully, but the PrePoMax importer does not seem to recognize the orthotropic material definition.
Here is a minimal working example that fails when imported into PrePoMax:
*NODE, NSET=Nall
1, 0., 0., 0.
2, 1., 0., 0.
3, 1., 1., 0.
4, 0., 1., 0.
5, 0., 0., 1.
6, 1., 0., 1.
7, 1., 1., 1.
8, 0., 1., 1.*ELEMENT, TYPE=C3D8R, ELSET=Eall
1, 1, 2, 3, 4, 5, 6, 7, 8*MATERIAL, NAME=ortho_mat
*ELASTIC, TYPE=ENGINEERING CONSTANTS
** E1, E2, E3, nu12, nu13, nu23, G12, G13
150000., 10000., 10000., 0.3, 0.3, 0.2, 5000., 5000.,
** G23
5000.*ORIENTATION, NAME=or
** Xa, Ya, Za, Xb, Yb, Zb
1., 1., 0., -1., 1., 0.*SOLID SECTION, ELSET=Eall, MATERIAL=ortho_mat, ORIENTATION=or
*NSET, NSET=FixedNodes
1, 4, 5, 8
*BOUNDARY
FixedNodes, 1, 3, 0.0*STEP
*STATIC
*CLOAD
7, 2, 100.
*NODE FILE
U
*EL FILE
S
*END STEP
When importing this into PrePoMax, I get the following error messages:
Error: Failed to import elasticity: *ELASTIC, TYPE=ENGINEERING CONSTANTS
150000., 10000., 10000., 0.3, 0.3, 0.2, 5000., 5000.,
5000.
There were errors while importing the file/files.
Is it possible to import orthotropic material definitions into PrePoMax?
I found one older post on this forum about this, but the answer was not clear.
Thanks!
