Mr. Sathish,

it looks to me your computer is not having enough memory space to run the program, As you know in any software program, the temporary files will be stored and used during the calculation phases. For example: global stiffness matrix will be stored temporarily and accessed for calculation purpose. The stiffness matrix size depends on the size of mesh. so check your computer has enough memory space to run the particular software program or not.. ok all the best..

Thanks Sir..
