I'm trying to run a simulation with the AIFlow Solver and the Caculate Loads option, but Elmer crashes with a segmentation fault.
The bug only appears when I activate the Calculate Loads option.
After looking in the code I have found that the problem comes from the fact that the BulkValues and BulkRHS variables of the solver matrix are not associated. Thus, Line 12754 of the subroutine CalculateLoads in the SolverUtils.F90 source file, the Aaid % Values and RHS variables are replaced with non associated values, which leads to the segfault during the matrix and vector multiplication (in the CRS_MatrixVectorMultiply subroutine).
I have tired to modify the source code of the AIFlow Solver by adding
Code: Select all
Solver % Matrix % BulkValues => Solver % Matrix % Values Solver % Matrix % BulkRHS => Solver % Matrix % RHS
Would anyone have an idea on how to properly fix this segfault error ? I have attached a small test case to the post.
Thanks a lot,
