It didn't change anything with the Boltzman-constant. Here are some files which could help you to understand better the problem: 1: The temperature in an element on the surface of the machined surface...

I set the absolute zero temperature, but not the boltzmann-konstant. I am going to try that. Really thank you for your help Vumat721.

I specified an initial temperature of 293K with a predefined field. But there is the problem without too.

Yes I had solved the problem but it's good for the forum's users.

Thank you for your replys Eser and Vumat721. I already tried to turn alternatively off the heat generation and the inelastic heat fraction but it doesn't change anything to my problem. And I still have the problem. Any other suggestion?

Hi guy, I would be really happy, if you could help me to solve my problem !! Here is it: I study residual stresses induced in orthogonal cutting. The simulation is "dynamic-explicit-temp-disp" The workpiece is modelled with a Johson-Cook law, conductivity, heat capacity, inelastic heat...

Dear all, Perhaps can you help me...I hope! 1) In a first simulation is my workpiece deformed. 2) I import it, (so I have now an orphan mesh), I delete one element, I create another element, and I use a predefined field (initial state), coming from the first simulation(1). 3)I launch the...

But I my case, if the stress in some elements is high enough, I want to change the geometry of my model...So I need to update the mdp no?

In your *.inp file: *Surface, name=..., region type=eulerian Doug

I am not sure to answer to your question but you can use the PredefinedField function to assign the last stresses to your new nodes.

Dear Abaqus users, I am writting a Python subroutine which should do something for each computed frame. But how can I access to this frames in Python? Or how can I run a job frame by frame? Example: p=mdb.jobs['JobName'] p.submit() "I would like to compute the next lines for the first...

Hi, There is something I don't understand with the 2D ALE adaptive meshing: I have two different models using this method but two different results. First model: a first step without ALE, a second with ALE: one inflow and one outflow eulerian boundary regions. The mesh moves with the material...

From your orphan mesh you can build a geometry with the following commands: orphanPart=mdb.models["Modelname"].parts["Partname"] mdb.models["Modelname"].Part2DGeomFrom2DMesh(name="newpart_name",part=orphanPart,featureAngle=0) ++

Hi everybody, Postprocessing my ODBfile ,I am trying to get access to the mises stress at some nodes of my model and I want to do that with a python subroutine (not in the visualization module !). Getting the nodal coordinates is not a problem, getting the stress of the elements is not a...

Thanks for you replies. You were right Xerf, it's worked well for me . But I would like to ask an other question on this theme: Performing an ALE, how do you fix the mesh in the space independently of the material flow ? On the in- and outflows surfaces of my model I defined eulerian boundary...
