transformation should work if no dof is constrained more than once, e.g no equalDOF and sp. we don't yet follow the path. for the lagrange you probably have to change the convergence test, disp increments for penalty and unbalance for lagrange. as for the penalty it should give you the correct respo...

you are probably using the dispBeamColumn .. use the (forceBeamColumn) nonlinearBeamColumn instead .. given nodal disp the force based element iterates to get a displacement field which exatcly satisfies force equi of element (force field known exactly for force based element) .. the displacement ba...

the problem is tcl/tk .. they have tightened up their api betwen versions 8.3 and 8.4 .. a lot of procedures now take const char * instead of char * .. as we have developers trying to compile with both versions we have defined TCL_Char in OPS_Globals.h .. if you look at the OpenSees files that call ...

can you be a bit more specific. you could for example use loadControl and in 1 pattern place the loads which use one path and in another specify the displacements which follow some other path .. this is IMPOSED DISPLACEMENTS and NOT DISPLACEMENT CONTROL :twisted: Most people want displacement cotrol...

ansewrs to your questions: 1. nodes and elements DO NOT have to be continuous. 2. you just have to enter 2 DIFFERENT nodes, remember the material for the ZeroLength will define the force-deformation and not stress-strain relationship. the 'strain' sent to the material at each step will be the differ...
