Hi everyone,
I faced a problem when applying gravity forces in FSI simulations. The gravity forces were applied on the surface of structure using CalculiXadapter, as follows:
*DLOAD
Eall,GRAV,9.80665,0,0,1
However, once adding the above flag in solid input file (owc.inp), the following error occurred:
Starting FSI analysis via preCICE using the geometrically nonlinear CalculiX solver...
Using up to 1 cpu(s) for the stress calculation.
Using up to 1 cpu(s) for the energy calculation.
Using up to 1 cpu(s) for the symmetric stiffness/mass contributions.
Segmentation fault (core dumped)
I have tried using ccx_2.19 to separately calculate the structure part, the calculation was completed with no errors. Thus, I guess the error may be related to the Calculixadapter
Does anyone have ideas about it? Many thanks in advance!
