contact_distance_factor and wall temperature don't work together

Hello,

I'm trying to use contact_distance_factor while imposing a wall temperature, but it doesn't calculate the particles temperature (nor hettran) instead "-nan" appears.

I tried modifying the example "in.heatGran" (attached) by adding contact_distance_factor and wall temperature and the same thing happened.

Do you have any idea how I can solve it?

I hope you can help me.

Best regards.
