Problem Defining terrainBlockMesherDict, point swl to stl
Hi to everyone,
I am currently trying to figure how terrainBlockMesher utility works, but I am having some problems with the Dict file. I have defined everything like is told in the tutorial and I have adapted the file to my case, but the same error appears with any modification.
Could somebody help me with this problem? I will appreciate it.
THE ERROR FILE:
PHP Code:
Create time
Reading stl surface...
...done, after 0.01 s.
Running TerrainManager
Selecting transition function type 'linear'
loading block grading module
found 5 regions for block grading in direction 1.
found 1 regions for block grading in direction 2.
