Dear all;

I am trying to create a simple example to learn how to use discrete element method in Abauqs 6.13 explicit solver, I started with the provided example (Mixing of granular media in a drummer mixer) but I faced a problem with defining surfaces for discrete particles where the contact is not working,

I created a deformable plate and used attachment points to specify the initial location of my discrete particles, then I used the keyword editor to add (*. Element, type=PD3D, elset=*****) and (*.Discrete section, elset=****,.....) which define these discrete particles, I then generated an input file and defined (*surface, type=element, ....) and (*contact inclusions ......). The input file is then imported to create a model where the input file reader does not supported and therefore the defined surfaces for discrete particles are not created. This is the message I got

WARNING: The following keywords/parameters are not yet supported by the input file reader:--------------------------------------------*DISCRETESECTION

It is possible to redefine the discrete section again through the keyword editor  but this is not possible for surfaces which is why the contact in my model is not recognised these particles and therefore they passed through the model.

any suggestions?

thanks
