Hi everyone, I'm new in crash annalysis, I've performed a simulation por a roll cage with 2d elements, but I got the error id 760, may someone can help me to find out whats the mistake
thanks in advance

Hi,
Update the element types (2D page>>elem types>>select 2D & 3D option and select all the elements, click update) in the model.
<?xml version="1.0" encoding="UTF-8"?>
Also for the output block there is nothing specified for the data variable. Input DEF for data variable so that all default variables will be extracted.
Update these in the model and run the analysis.
The same updated model is attached along.
Thank you very much George, it works!!! I appreciate your help...
Hi everyone, I´ve run the analysis but something went wrong, as I show in the picture attached the roll cage goes trought the wall (I've performed the simulation following the car pole tutorial), may someone knows what is happening?..., I'd appreciate any help
Have you made the wall using rigid wall option, if yes check the normal , it should be opposite to direction of motion and also see if you have added slave nodes i.e of rollage to rwall or not?
if not made using rwall, kindly check the contact between two parts.
Thank you very much for the help, I changed the normal direction,. but now I got the message:
** RUN KILLED : TOTAL MASS ERROR LIMIT REACHED
2000 0.2908E-03 0.4597-125 NODE 1192 0.0% 3870. 0.7653E+14 577.8 0.000 Infinity
something is missconfigured, I´m attaching the .out file; also the .hm file, maybe somebody can take a look to it...
Hi, There seems to be some issue in modelling. Check the node no.1192 and also part no. 4 where the highest kinetic energy is seen. This might be due to node shooting , that needs to be checked in animation.
Pleas share .rad file i 13 version for review
@Robert65
Looks like no slaves nodes are provided in rigid wall definition, can you please check the same?
Also, I think the problem is with the velocity, from the out file I see that the KE is very high, reduce the velocity and check if that helps.
Or impose small time step and check if that helps.
