Hello all, Can somebody give me some idea that which material to use for my springs (trusses basically)? I want an E value of 0.01 on tension side and E = 10000 on compression side of my force deformation relation. Right now I have assigned ElasticBilin Material for which I have assigned following p...

Hello, Can you tell me how did you fix this problem of running out of memory. I have a TCL routine and I keep getting this error: WARNING BandGenLinSOE::BandGenLinSOE : ran out of memory for A (size,super,sub) (19986, 6659, 6659) StaticAnalysis::handle() - LinearSOE::setSize() failedStaticAnalysis::...

Hello vesna, Sorry to post again but is it necessary to define material and section each time we change the domain ?? Because if I am not doing this than it gives an error when routine tries to create truss element : UniaxialMaterial *getUniaxialMaterial(int tag) - none found with tag: 7 WARNING: In...

Hello vesna, I tried implementing your suggestion and it worked fine for the simple model given in my above post but when I tried that in my bigger model which has around 4438 nodes, It gave me following error: WARNING BandGenLinSOE::BandGenLinSOE : ran out of memory for A (size,super,sub) (19986, 6...

Hello administrators and everyone, I am new to opensees so I will appreciate any help.I have modeled a column-base connection having standard brick and shellMITC4 elements connected by truss elements. brick elements are acting as cement grout and shell elements as base plate and the load interaction...
