Topic: Modelling problem

Sir,after the reading the troubleshooting problem,still my problem  is  not solved .These are the error i am getting...

Invalid master-slave BC, selections for master(s) Contact_MASTER_Interval1, for slave(s) Contact_SLAVE_Interval1 : at least one of decorated dofs  in slave nodes 459, 532, 813, 858 could not be constrained, specified in support id: 13, load case id 1, name: LoadName disp 1; BC ignored. (Source line: 425, file: ..\..\Sources\CCSupport\assemble_lhs_bc_slaves_list_by_masters_list.cpp, last modified at: Fri May 22 16:28:45 2015)

Warning: Attempt to constrain slave/use master non-active or zero dof: 1 of node: 459, load case: 1, dof BC: 1, LHS BC id: 1576; constraint  ignored. (Source line: 55, file: ..\..\Sources\CCLhsBC\check(CCLhsBC).cpp, last modified at: Fri May 22 16:29:19 2015)

Re: Modelling problem

Dear parimals,
1. next time, please continue with follow-up questions in the original thread.

2. It is not 100% clear if you followed all suggestions from Troubleshooting, 2.4.4 I get the warning "Invalid master-slave" during analysis, what is wrong? and 2.4.6 Floating point problems - Division by zero, Loss of >7 digits on the matrix diagonal, CCFEModelExc: CCPardiso solver error: zero pivot,  Warning: Sign of diagonal changed when reducing equation, Floating point exception: Multiple floating points traps, Zero or negative jacobian,  InvertA: zero determinant, CCMaterials Extended AExc: CC5ParamYield F: project_stress_on_f_division by zero, and similar?

3. If you still can not solve the issues, please follow Troubleshooting, 2.1.1 to send us your model etc.

Regards.
