Hi,

I am trying to run a CFD model using the batch mode but crashed with some Java errors. The same model runs fine using the GUI (comsol client) and a Comsol Server.

OS: SLES 11
COMSOL version: 4.0a

The command I used:

comsol batch -inputfile in.mph -outputfile out.mph

The result:

...
Running: Transient run (turn on weak contributions)
Time-dependent solver (BDF)
Number of degrees of freedom solved for: 24144.
Current Progress: 0 %
Memory: 561/561 2072/2077
Nonsymmetric matrix found.

Anyone knows what the "Could not find the service 'com.comsol.nativeutil.h'" error refers to and how to fix it?
