Hello Reno,

I apologise for the late response. I have tested the new LS-DYNA version and it seems to resolve the issue, now both ELFORMs couple with the EP solver.

Is there an object version of LS-DYNA R14 available, as I am using a user-defined loading condition to couple the left ventricular model to a 0-D fluid circuit?

Thank you for helping me resolve the issue.

Best Regards,
