FOAM exiting

This is the error I receive when trying to run a program from a 3 yr old Heat Transfer tutorial https://youtu.be/Nhhm-ZPxVRc?si=9P15Zi3DpA9oKFSm

Here is my fvOptions file

Hi,

The error says that the options part does not have a type entry. Probably you have a level of {} too many. Try this:

}

It may then throw a different error, as syntax may have changed in three years.

Hope this helps.

Thanks,


That helped to generate a different error. Unfortunately, I am quite inexperienced with openFOAM and have very little idea of what to do next. The number of changes between versions makes it very difficult to learn from scratch.



Here is the new error I receive:

Hi,

Indeed some of these changes can be difficult to trace back. However given the name, I guess you should use semiImplicitSource.

The link above will give some more information on the usage as it is implemented in v11. You may need to "translate" your setup to the new syntax.

Good luck,
Tom
