Does there any way to resolve this issue??. I have used " UMFPACK" solver.

Thanks in advance.

NO and Yes,

You can try with MUMPS_seq , or try to use parallel solver like PETSc ,

Thanks sir for your replies. Can you help me to install parallel solver like PETSc in FreeFem++??. I am facing problem to install and use it.
