Error when running a modified OpenFAST model although compilation was successful

[relhamoud]

Hello everyone,

I modified the source code of openFAST more particularly the StrucCtrl.f90 in order to account for an external force in the aim of an active structural control using an active TMD. The compilation was successful. However, when running openFAST as usual the following error occurs:

Running ServoDyn.

Could you help me please in understanding and fixing the error?

Thank you in advance.

Best Regards,

Dear @relhamoud,

A program exception access violation error typically occurs when you are trying to write to a memory location that is inaccessible or outside of the process address space, for example, writing to an element of an array that outside the bounds of the array.
