Need Help, Probably Doing Something Simple Wrong

Altair Forum User

Hello I'm new to using hyperworks and have been thrown in the deep end. I took over for a PHD's paper whilst he is on holidays. I have been given a model that im trying to get to run in radioss, but says 'Process encountered an error' 'Run Number too Big'

I'm hoping this means something to someone but I will go through what I was told to do and maybe some one can pick up on what I'm doing wrong.

I was give the model by the Doctor before he left with little instruction so this is what I did.

The file is to simulate a train smash into a wall. A rigid wall has been placed in front of the train.

1. Opened the file

2. Went to Utility -> Bc manager-> Inputs

Name V20

Grinod Parts selected all parts

Initial Velocity

Entered in Velocity

Then created it

3. Created a Memory- Tools -> Creat Cards -> Control Cards -> Memory-> Nmots 75000, Real 0 ***** (could be wrong, unsure)

4. Utility -> Engine File

General

T- 200

Time Freq- 0.01

Anim Top left and bottom right box checked.

Top left output-

Elem Epsplastic

Elem Vonm Stress

Elem HourG

Bottom Right output

Vel

Cont

Fopt

5. Export Document.

6. Open on Radioss takes about 10 seconds.

a few lines of C:\Altair\hw10.1/hwsolvers/bin/win32/hwsolver.bash: [: -lt: unary operator expected

it then says ---- Run number too big

Process encountered an error.

There is no radioss logo, which means I have missed something that is esstenial to simulate it.

Hope there is enough information to diagnose my problem, if not I have taken some screenshots that I can email (was trying to put up on this forum but had no luck).

Thanks in advance,

Matt

Use radioss starter and engine files seperatley, do not use *.bat file, sometimes it does not work depending on the release and update.

Create your own bat file like:

'C:\your_altair_dir\hwsolvers\bin\win64\your_starter.exe' -input your_model_starter_file

'C:\your_altair_dir\hwsolvers\bin\win64\your_engine.exe' -input your_model_engine_file -nproc or-ncpu cpu_count

Check out the forum for the parallel solution process, I had wrote something about that.
