geometric transform problem

[martinmasanes]

I set the geomtranf parameter as shown:
set transfTag_C 1
set transfTag_Brace 2
set transfTag_B 3

# rigid links of columns; columns
geomTransf PDelta $transfTag_C

# braces, gusset plates
geomTransf Corotational $transfTag_Brace

# beams
geomTransf PDelta $transfTag_B
#set beam element (only 1 as example)
element forceBeamColumn 11201 1210100 1210100 3 $secTagB $transfTag_B -iter $maxIter $tol

but I get this message:

PDeltaCRDTranf2D::ComputeElemtLenghtAndOrien : 0 lenght
ForceBeamColumn2D::setDomain():Error initilizing coordinate transformation

Thanks!!!!!!!!!!

it looks to me that in your model you have force-based element of zero length.
