I'm Trying to make a model using PFC2D software. Does anyone have an idea about how to rotate a combination of walls and balls. What I'm thinking about is to rotate all position vectors of all balls using "Rotation Matrix" but I don't know how can I start!

 I'm also looking for PFC2D Tutorials or any complementary examples.

 I would be thankful if you could help me?

HI everyone,

 I'm Marjan, I want to do modelling a 1-D freezing problem with ABAQUS. This problem naturally contains "Heat and Mass transport". 

so, I want to use "UMATHT" subroutine in ABAQUS, but I have a problem with that. I know that this subroutine will be called at all material calculation points of elements for which the material definition includes a user defined thermal material behavior.

 --> General--> User material:user material type: thermal

 then, I need to define "thermal constants"

My question is " what constants should I define"?

 If you have any example problem or tutorial related to this sort of problems, please let me know...
