Memory issues
What kind of error will be displayed in OpenSees when there is not enough available memory for a model to be constructed and analysed?
From what you are saying it looks like memory is not the issue. I have been modelling various soil foundation models under both linux and windows. There are layers of 8 node brick elements for the soil material and either piles or shallow foundations. Depending on the model, a certain number of soil levels can be used in the model and it will run fine. But if i add one extra level of soil to the model an error message is output

StaticAnalysis::analyze() - the Algorithm failed at iteration: 0 with domain at load factor 1
OpenSees > analyze failed, returned: -3 error flag
All the constraints are the same for each level except the base, so i cant see why this error is occuring, as with one less level it runs fine

try different solver
Hello Liam,
Try different solver and see what you get?
