Q. Two different rigid constraint equations are generated and saved to file.s01 and file.s02 files.
When user attempts to run this solution with LSSOLVE,1,2,1, he gets:
**************
Error:
Constraint equation 1 does not exist. The CECMOD command is ignored.
**************
He can do this without error using sequential solves without leaving solution.
What is the problem?
A. It is a code limitation regarding CERIG and LSWRITE/LSREAD. At 10.0, we will document that
CERIGID cannot be deleted by using cedele,all and regenerated, in the 2nd load steps or higher if LSSWRITE
and LSSOLVE procedure is used. The reason is that CERIGID generates CE's directly put into load step files (
jobnames.s01, .s02, ...). The deletion of CE (cedele,all) cannot always maintain the consistency among
load steps.
