Hi all. Does the Johnson-Holmquist model not work in the Ls-Dyne Workbench?

I did sandstone cutting from the WB base, this is what happened:

Then I put in a Johnson-Holmquist material snippet (I also put in a SECTION and PART snippet to specify what material to use for the part, I created the snippet in the GEOMETRY - INSIDE MODEL section):

but the calculation stops with an error, but there is no error text:

hi 

do you have any refernce to your work ?

do you have any formal /guided training in LSDYNA in general ? and specific to paticel methods? , if not i suggest you first get the training started.

how can you run 16 cores dispite the licenses you hold?

JH and JH-2 will run in lsdyna wb if executed properly !

 SECTION and PART snippet will not be taken under the GEOMETRY, you need to use the opton in the LSDYNA -PRE tab. 

cheers, Ram

Sir SECTION and PART is of course used in LSDYNA -PRE tab. But I have another question, where to put the snippet with the material? Here I wrote:

I created the snippet in the GEOMETRY - INSIDE MODEL section

if you put a snippet with material there, then it will be written to a k-file. if you only put it in the LS Dyna PRE, then the workbench will not see it. How to do it right?

>>JH and JH-2 will run in lsdyna wb if executed properly !

thanks, so you need to clarify where to correctly insert the snippet with the material and how to do it correctly and continue the calculations with a finer mesh of particles. Looking forward to your tips and advice! Thank you.
