Hi everyone, I am using DigSilent PowerFactory software for a project. The grid is shown in the picture below. My question is considering the DC link shown in the circled part of the grid. When I try to simulate the short circuit on that side he gives me this message **** warn - Max. short-circuit current contribution of converter PWM Converter/1 DC-Connection 2 is zero
warn - Cannot compute a short-circuit at a DC line 'Grid\Terminal(1)'.
warn - Cannot compute a short-circuit at a DC line 'Grid\Terminal(2)'.
warn - Short-circuit is not calculated on the following de-energised busbars:
warn - 'Grid\Terminal(4).ElmTerm': ***
Any tips or ideas what can be the issue?
Thank you very much in advance.

Qamar Ul Islam thank you very much for your answer. Yes, I also changed the method to IEC61660 (DC) and now I get this message concerning my system? Any ideas what can be the issue?
