When I use calculix to deal with fluid-structure coupling problems, I need to use calculix often. I use *restart, read to ensure that calculix inherits the previous calculation results. However, after running for a while, calculix failed to generate.frd file: : *ERROR in u_calloc: error allocating memory
I am using the ccx_2.20 version, can anyone see the reason for my error message? How should it be corrected?
The following error message is reported:
