Can anyone help me with the use of Birth and Death Elements with the Advanced Nonlinear Solver for Femap?
I am carrying out a repair on a truss where I need to cut and replace a section of the top flange of the bottom chord. Prior to cutting the top flange I will weld in a "dummy flange" to suppor the loads during the repairs.
I want to use birth death elements as follows:
Step 1 - Run the model as the truss currently is
Step 2 - Run the model with the "Dummy flange" installed
Step 3 - Run the model with the dummy flange in and the top flange removed
Step 4 - Run the model with the dummy flange in and the top flange replaced
Step 5 - Run the model with the top flange replaced and thedummy flange removed
As I haven't used Birth Death Elements, I am only trying to get Steps 1 and 2 currently.
In the nonlinear solver I have put in he following text:
Under Bulk Data I have input
EBDSET 1 1 2 76 THRU 82
When I try and solve the model, I ma getting issues stating "The Begin Bulk Statement is Missing".
I am not very familiar with writing code for nonlinear solver functions, so any help would be greatly appreciated.
