 1. prepare input 
 2. edit config.yaml
 3. run main.py

 # FAQ / Troubleshoot
 
+- error at import data:
+	- check data format
+	- check CRS of data
+	- check domain definition (center, corners)
+	
+
 - main.py stops at meshing, error:
-check if Pointwise is installed and in PATH
\ No newline at end of file
+check if Pointwise is installed and in PATH
+
+
+- fluent crashes on 1 node:
+	- probably not enough RAM: increase number of nodes per simulation
