Calculating 3D Thermal Bridges

In order to calculate 3D thermal bridges (such as any "point" thermal bridges), THERM, my go-to program for 2D ones, cannot be used.

Such a 3D thermal bridges would be for example steel rebars in a concrete floor protruding to form a balcony. Or steel pillars for a raised-floor system above a built-up roof.

I was wondering what tool people use for that and what are the pros and cons of the tools they've used.

Especially, if anyone has an open source or very cheap alternative, I'll take it. It doesn't make sense to buy very powerful and expensive tools if you're going to be using them only a handful of times for simple problems like this. For example I've tried Comsol which is great, but out of my budget by a factor of 10 at least.

If you are aware of any library of common 3D thermal bridge values, I'm interested as well.

I was wondering what tool people use for that and what are the pros and cons of the tools they've used.

Especially, if anyone has an open source or very cheap alternative, I'll take it. It doesn't make sense to buy very powerful and expensive finite element method tools if you're going to be using them only a handful of times for simple problems like this. For example I've tried Comsol which is great, but out of my budget by a factor of 10 at least.
