I get "segmentation fault (core dumped)" error running on tutorial.
1 Attachment(s)
Hi i am newbie in openfoam, i did draw a simple geometry in solidworks, i did mesh it with salome 8.4 NETGEN 1D-2D-3D (Image 1) and i saved it as a UNV file. Then i import openfoam7 with ideasUnvToFoam utility and i reorganize my boundarys like below downside. When i checkMesh there isn't any error but when i run my case with icoFoam i get the error which below downside. At first, code running like 5-10 second. How can i fix this, any suggestion?
(This case based on, incompressible/icoFoam/elbow tutorial.)
Code:
