Hi,

I trying use a (nonlinear geometry) solid model

StVenantKirchhoffOrthotropicElastic to simulate BeamInCrossFlow tutorial

but i get this error:

Code:
 
--> FOAM FATAL IO ERROR: 
Unknown mechanicalLaw type StVenantKirchhoffOrthotropicElastic

Valid nonLinearGeometry mechanicalLaws are : 

12
(
rotationInvariantLinearElastic
isotropicFungElastic

I use OpenFoam 9 with solids4foam V2 in Ubuntu 22.04. The installation had no problems.
In verification of installation with ./Alltest only there is two error, but it is because in solidProperties file coefficients is not defined (fixed).
Code:
                         Preparing logs
 
 
 Summary statistics
     Number of cases where a run was attempted: 41
     Number of cases where the solver failed: 2
     Number of cases where another command failed: 0
 
 
 The solids4Foam solver failed in the following cases:
 Application solids4Foam - case beamInCrossFlow: ** ERROR **
 Application solids4Foam - case flexibleDamBreak: ** ERROR **
I also used:
Code:
> git checkout development 
> git pull 
> ./Allwmake 
> ./Alltest
To verify installation, like this post


The linearGeometry model to Orthotropic is working and beamInCrossFlow orthotropic works.

Code:
type orthotropicLinearElastic;
Note: in /home/andy/solids4foam/src/solids4FoamModels/materialModels/mechanicalModel/mechanicalLaws/nonLinearGeometryLaws/ exists:

Code:
StVenantKirchhoffOrthotropicElastic:
StVenantKirchhoffOrthotropicElastic.C  StVenantKirchhoffOrthotropicElastic.H
Is this model not compatible with openFoam 9?

Hi Andy,

have a look into Make/files.openfoam and Make/files.foamextend and you will see that the StVenantKirchhoffOrthotropicElastic model is compiled only using foam-extend. You can switch to foam-extend or adjust the code to be compatible for openfoam9.
