i did everything on tutorial but i had so much error then i changed element type on 3D to penta6dg then i changed properties to p20_tshell with Isolid=15 then became 2 errors

Hi
Can you change the property for air and water to solid instead of thick shell.

When i did solid , i have so much errors , its code is 639 and there are 26 errors with solid

your tutorial is worked , but i did like that everything , what was my mistake ?

The problem is with the penta elements.
PENTA6 is somehow causing the problem and update penta element type to PENTA6DG. This works.

Hello,
I try to learn Radioss via tutorials. I run RD-3560 tutorial yesterday. But running have not finished yet . I think, the model is not big so running process should not take long time. Is there any problem? you can see .out file in attc.
Thank you

Hi Nihan,
From the out file we can see that the time step has drastically dropped, and that's why the run is taking more time to complete.
This time step drop can be because of an element, a node or an interface.
•For an element, check the related material (especially its Young modulus and density in case of an elastic-plastic material; and its viscosity in case of a visco-elastic material). There must not be an error in the units system that this data is given in.
Check the size of the element, since elemental length is proportional to time step.
•For a node, check the characteristics of connected elements. If the node is on the master side or the slave side of an interface, this interface must be verified.
•For an interface, the gap of the interface must be verified if some failure happens on the master or the slave side of the interface.
Once this is cleared you can run the simulation without time step being dropped.
In this case, it is an element and you can check the parameters mentioned. If the issue persist, please share the model file.

Hi @Addy,
Can you check whether /PART card image is assigned to the components?
If it is assigned, please check whether property and material are assigned to component(s). Also, check the compatibility of property, elements used, material etc...
Can you share the complete starter out file, please?
0 -
Yes PART card image is assigned. I am Sharing my hm file here. Plz check it and help me out. Thanks

What was the error? I am unable to identify?

Hi @Addy There are few PENTA6 elements in Water and Air components which are not compatible with LAW37. So, changed the element type to PENTACG,

Hey Prakash.
Still same issue. Again it is saying property not assigned

Hi @Addy
The file runs fine at my end. This could be due to version issues.
Please apply property and try again
