Hello,

I am currently trying to follow along and test the electrophysiology tutorial keyword files that are provided on the LS-DYNA tutorial pages (https://www.dynaexamples.com/em/epintro).

I’m able to run the electrophysiology ventricle arrhythmia file (Case 7 from tutorial) using R12.1 MPP double precision, however, for case 10 with the biventricular heart model, I’m unable to get it to work with any version of MPP double precision. I’ve tried all versions from R11, R12, R13 and R14.I was kindly wondering if anyone would be able to let me know what version of LS-DYNA that will allow me to run the model? I noticed when opening it up in Notepad ++ that it says at the top “Required LS-DYNA MPP DEV-96951 or higher with double precision”, however, as I’m not a developer I don’t have access to these versions.

Additonally, one of the errors is stating that there is a missing keyword file in the package that I don't seem to have access to.

Thank you in advance, Grant.

Hello Grant,

Have you tried with the latest R15.0.2 solver?

LS-DYNA (user=user) Download Page (lstc.com)

If R15 does not work, then you will most likely have to get a DEV solver.

If you are a commercial customer, you can create a support case:

If you are an academic customer, please contact your Ansys account manager to see how you can get support to get the DEV solver.
