Analysis problem in a pile-soil-raft-superstructure modeldel

[rajib.iitbbsr]

Dear sir,
A 4X4 pile group-raft supporting a 3D frame superstructure of single story is done in opensees with the help of suitable element and materials. Soil is defined by zerolength spring element spring.
Plz anybody will check my code why analysis is showing an warning. The warning is as follows:

"WARNING UmfpackGenlinsolver::solve(void)-4 returned in factorization UMD2FA()
UMD2FA: LVALUE too small! Must be greater than 1934196" ..................

The final code is also attached for reference.

Plz help me.....

this is a problem with the solver running out of memory in it's work area .. the next version of the code will have a fix .. in the meantime you need to use a different solver .. how big is the model and do you have multi point constraints in there.
