Title: error-Insufficent storage to allocate TANGS
Post by: ashish on January 21, 2015, 09:25:49 PM

hello sir,
sir i am trying to solve 3-dimensional plate problem by modal analysis.I need to validate my result with feappv for that i want fine mesh of plate.But feappv software showing some error after 10500 node.

Error
Insufficent storage to allocate TANGS         
check data or choose another option.

either FEAPpv have some limitation means  can we solve upto 10500 node only???         
I am looking forward for your responce.

Thank you very much.

The problem is not FEAP it is your computer.  Your computer has insufficient memory to solve the equations.  You could try using the iterative solver (ITER); please see the manual.

Also, is the mesh irregular.  Be careful how you number nodes.  FEAPpv does not have an iterative solver.

If one looks in pmacr.f and pmacr1.f, one sees the iters (diagonal preconditioner) option.  So I think it is there.
