Ceetron Solve can log the call-stack of the supported objects to an Echo File, which could help the support team debug a given problem. This shows how to set this up in your application.
Initialize the Echo File:
vsy_Echo* echo = vsy_EchoBegin();
vsy_EchoOpen(echo, "callstack.echo", ECHO_WRITE);
Add the Echo File to the supported objects, e.g.:
vfs_DofTab* doftab = vfs_DofTabBegin();
vfs_DofTabSetEcho(doftab, echo);
....
vfs_SysMatrix *sysmatrix = vfs_SysMatrixBegin();
vfs_SysMatrixSetEcho(sysmatrix, echo);
....
vfs_SysVector *sysvectorb, *sysvectorx;
sysvectorb = vfs_SysVectorBegin();
vfs_SysVectorSetEcho(sysvectorb, echo);
....
sysvectorx = vfs_SysVectorBegin();
vfs_SysVectorSetEcho(sysvectorx, echo);
....
The Echo File must be added just after the *Begin() call and before any other call in order to track all the subsequent calls to those objects.
