strange problem with data

seav · April 11, 2014, 06:01

Hello FOMERS.

I dont know how to name my problem properly so it goes like this.

The problem is really strange for me. I want to make simple-test-checking simulation with setting and naming internal faces. I made simple blockMeshDict with vertices, blocks and patches. I created starting 0/ folder, system/ folder etc. and run my calculation without any problem. I was supprised when I was checking data collected.. 1st step at boundary conditions seems to be good, but then 2nd and whole steps after are red.

GEOMETERY : Its a small box in bigger box. attach 1, 2

1st STEP : Seems be ok. attach 3,4
PROBLEM : Red planes after calculation. attach 5

blockMeshDict:
