JP, In some places in http://code.ascend4.org/viewvc/code/branches/slvreq/test.py?revision=2780&view=markup you have
M = T.getSimulation('sim',False)
and in some other places there you have
M = T.getSimulation('sim')
When in robust.py I replace M = T.getSimulation('sim',False) with M =
T.getSimulation('sim') I am getting shouted at as shown in
console_output. What is happening?
Regards,
DFE
