UmfPack error in retaining wall Analysis

[Rubinsa]

Hi, I am trying to model a retaining wall. The wall is dispBeamCol element. I use beamcontact2D for soil wall interaction. when I use UmfPack for the analysis process, the model only is able to excavate one layer of soil and then it will give me an error for the other steps as below:

WARNING: symbolic analysis returns -8 -- Umfpackgenlinsolver::setsize
WARNING:UmfpackGenLinSOE::setSize : solver failed setSize()
StaticAnalysis::handle() - LinearSOE::setSize() failedStaticAnalysis::analyze() - domainChanged failed at step 0 of 1
OpenSees > analyze failed, returned: -1 error flag

Could anyone help with that?
Thanks,

try changing solver to ProfileSPD and respond with the error you get when you run it
