OpenSees running is normal, but once useing of SP module by mpiexec –n OpenSeesSP.exe on XP 32bit /Win7 64bit always show the following error.



FEM_ObjectBrokerAllClasses::getNewUniaxialMaterial - - no UniaxalMaterial type exists for class tag 48

FiberSection2d::recvSelf -- failed to allocate double array for material data



Consult everybody, whether the SP module does not support the initial stress material, or there are other alternatives.
Any help will be appreciated.

i have fixed the problem in the source code .. the plan is to release the new version this wed, which will incllude the code change

Thank fmk.
