Dear fmk,I have found the problems. If I build model with 2dof first, then the 3dof , I have to apply load to nodes with 3dofs. I build model with 3dofs first, then it is OK to apply load to nodes with 2dof. model BasicBuilder -ndm 2 -ndf 2 source tunnel2.tcl source viscous2.tcl model BasicBuilder -...

My model contains nodes with 2dofs and 3dofs.I want to apply load to the node with 2dofs.If the command is "load 447 0 40 0",then it shows error message as "Node::addunbalLoad - load to add of incorrect size 3 should be 2" .It is OK during the gravity application stage,do you thi...

Thank you,fmk.Another question now,it is about the load .I want to apply a node force,but it shows errors. I find the same problem in this forul, but I could not solve it with that method. laod commad is : pattern Plain 1 Constant { load 447 0 40 } error message is : WARNING bad command - want: load...

I want to define a spring with a angle,that is to say the spring is not in horizontal or vertical direction.But the zeroLength element has the direction of "-dir 1 2".What could I do?

I have to post the tcl file for help .The tunnel is under the ground. During the elastic gravity application,the results are fine,but during the elastic-plastic gravity application,the results came abnormally,the displacement of he nodes became very large. Materials and element are: soil : PressureI...

My model consist a tunnel under the ground, subjected to cyclic load.The soil material is PressureIndependMultiYield Material,element is quadUP;for the tunnel,Elastic Beam Column Element is used;and for the lateral boundaries, viscous damper is used.There may be some problems in gravity applications...

I want to make viscous boundary for the lateral surface,and element type is quadUP。If the element is quad, we just need to define a zerolength element for viscous damper. But when use quadUP, 2 nodes for zerolength have different DOFs.Do I need to define it like the interface between pile and soil?

Thank you,jinlu.Another question here. As for models with PressureDependMultiYield Material, analysis step should be very large such as 5000,in order to make the excess porepressure dissipatied,but with PressureIndependMultiYield Material, the porepressure may not be very large, so how about the ana...

I want to build a model of a foundationl with size 50*50,and the size of mesh is 1*1.The material is PressureIndependMultiYield Material, coupled with FluidSolidPorousMaterial ,element type is quad. First,it is the gravity application.But when I update the material stage to 1 ,it could not pass succ...
