Hi,
I want to process a multipoint optimization with constraints. The problem I encountered is that, if I set OPT_CONSTRAINT=NONE or a flow based constraint function(e.g. MULTIPOINT_MOMENT_Z), the optimization goes well. But if the geometry based constraint is given to OPT_CONSTRAINT(e.g. OPT_CONSTRAINT=( AIRFOIL_THICKNESS>0)*0.001 like onepoint problem ), the error will occur as below. The cfg file is based on inv_NACA0012_multipoint.cfg that is from TestCase and it is put in the attachment.
I have no idea what the problem is. I can't find the answer anywhere else.

Has anyone ever encountered this problem?

Hi,
I have also encountered this problem, but i can not solve. Do you still encounter this problem? If you don't, how do you solve?
