Restart file 1_0000.0001.rst was not created

Hi, I tried to run the incremental radioss solver. I gave all the parameters and then when I run the solver, I get the following error that 'Restart file 1_0000.0001.rst was not created' and 'Missing normal termination in output file 1_0000.out'.

I have attached with the screenshot of the error.

Kindly help me in providing a solution as early as possible.

Thanks in advance.

Hi,

This error shows that due to some modelling error RADIOSS was not able to create the restart file for this run.

The error clearly states it's related to the material inputs. Please recheck the material created.

If the error persist please share the starter out (_0000.out) file.

Hi, can you kindly help. I need to add a user defined material. So in which format should the notepad file be created to add in the hyperform database. Can you share with any example file for the materials.

Thank you.

Hi, I am using Incremental Radioss. There are few default material available in the database. When running the simulation with those default material, the simulation runs successfully (though it has 0 errors and 2 warnings. The warning is related to the material property). But I am using a different material which I add it in the database manually. When running the simulation with the manually added material, I get the error in simulation running or the simulation gets stopped in the middle while it is running few animation files. In the summary page, I get 0 errors and 2 warnings, the same one which I got while running with the default materials. The difference is that, the simulation gets over when running with the default material but it isn't getting completed with the manually added materials.

The material I am adding is DP1200 steel.

Have attached with the screenshot of the error.

Error : 2 warning id :1084

Warning in material law1

When referring to material law1, it says it is related to the elasticity of the material. But I have given the input values properly.

Kindly help me as soon as possible and thanks in advance.

Hi,

Can you please share the out files?.

Altair Forum User

Hi,

Thanks for your help. I am using Hyperform 2017.1 version. I have added with the out files and the material file. Kindly refer to it.

Thank you.

Hi,

This is just an information given by the solver that for material law 1 the number of integration points used in property (N in property refers to number of integration points) should be 0. In your model you have used N value greater than 1 and so the solver automatically switched to 0.
You can continue with the run.

Ok thank you. But how do I evaluate the results? I do not get the .res files even after the simulation gets over?

Another doubt is that, when I run a new simulation with mesh size as 2.7 and the default available material CRDQ, the simulation stops in few min. For you reference, it is in the same animation file 7 for the past two days? Can I quit the process or still it is running? Can you please sort out this.

Thank you.

Hi,

This sees like some modelling issue. Please post the same query in HyperForm forum (https://forum.altairhyperworks.com/index.php?/forum/29-hyperform/) where our HyperForm experts will help you in resolving this.

ok I will post it in the other forum.

But can you kindly help me with evaluating the result file. How do I get the .res files? Or how can I evaluate the results without that file.

Also, it would be of great help if you could help me with the procedure for adding or editing the FLC curve (forming limit curve) for the material. The tutorial says it has an option for FLC under the setup tool. But I could not find that option in the setup menu.

Thank you again.
