Hi 

I was wondering if there is a way to simulate a wooden beam with one sided charring (burning), including material decay and density change and other material properties. 

Thanks in advance

Hi:

The best way to do this is by using a combined porous media and UDF approach.  The approach is documented in the following paper:

Numerical simulation of a burning cigarette during puffing
Mohammad S. Saidi1, Mohammad R. Hajaligol, Firooz Rasouli

J. Anal. Appl. Pyrolysis 72 (2004) 141–152

I am not sure if you have access to the ANSYS knowledge base articles, but a small test case can be found in Article 000087117
