Error in the dynamic analysis

Post by sreedharrao144 »

While analyzing i.e.dynamic analysis in 3D with shellMITC4 elements I am getting the following error. I used the section ElasticMembranePlateSection for those elements ans bottom fully fixed.It is blast furnace model.

LVALUE too small. Must be greater than 1773598
UmfPackGenlinsolver : : solve (void) -4 returned in factorization UMD2FA ()
I am getting out put files with 1.#QNAN. What to do and why this kind of error is coming? Please help me.It is very important to my carreer.

Try another solver (e.g., sparseSYM)

Thank you for the response vesna. I tried with Sparse symmetric solver.If I use SparseSPD it was showing "OpenSees.exe has stopped working" in windows explorer.Please help me vesna I will be waiting for your valuable reply.
