    Problem with density in a CEL abaqus

    Sadly I do not have any accesss to support (this is for my master thesis), my university only has the abaqus standard license. So I will have to figure something out.

    Problem with density in a CEL abaqus

    Hi all, I have been working on a tank simulation, when simulating this case I got this behaviour with the tank still https://www.dropbox.com/s/z4crh72au8rj14n/Ingtips1_50pc.PNG https://www.dropbox.com/s/4352ytpejc7nf8c/Ingtips2_50pc.PNG After posting in the FEM forum a colleague from this...

    Problem with explicit fem with solid-structure interaction in ABAQUS

    I have checked different properties for the materials and I have discovered that the steel density is the variable creating the initial problem (that's why the first file was working), when you increase the steel density by 100x everything works flawlessly but when you return to normal material...

    Problem with explicit fem with solid-structure interaction in ABAQUS

    Wow thanks! Now is working perfectly, but I have checked the interaction properties of the file you sent me and I can't see the rough friction between water: https://www.dropbox.com/s/2xr5dqqjnr7e897/no_rough.PNG Did you change it in a different place?

    Problem with explicit fem with solid-structure interaction in ABAQUS

    I have tried again and it does not make any change in the estable time increment, I do not know what to think. I am doing something wrong or I have something wrong with the file or the software. Have you been able to get the .cae file? No rushing or something like that, you have helped me a...

    Problem with explicit fem with solid-structure interaction in ABAQUS

    Still the problem of the thread happenig, I am doing something wrong. Could you send me the .cae that you modified to check both things? Thanks a lot.

    Problem with explicit fem with solid-structure interaction in ABAQUS

    Thanks again! 1. Found it! 2. I tried this but the calculation is still the same 4 min -> 0.01s, after changing the material properties did you change anything else? In the step definition or something like that? 3. Found it!

    Problem with explicit fem with solid-structure interaction in ABAQUS

    Sorry I have not answered before, BIG BIG BIG thanks! This is absolutely awesome. Although I still have to ask some things: 1. How you create this kind of rough friction? I have to add it apart from the All with self? 2. Did you do anything special to calculate so fast? Or just a powerhorse...

    Problem with explicit fem with solid-structure interaction in ABAQUS

    Yeah, I think the volume fraction is ok, but I have uploaded the .cae anyway so you can check it. Here it is: https://www.dropbox.com/s/4vyou5p470doexi/cisterna_sinvimiento_50pc_maseuleriano.cae I will delete it tomorrow. Thanks again, this one is tricky.

    Problem with explicit fem with solid-structure interaction in ABAQUS

    I have checked the units many times, they are in N/mm and I think they are Ok, although you never know. But I tried simpler things before (less fluid) and worked flawlessly. The only warning given is related to some thermal properties of the water material. I can send you the .cae file if you...

    Problem with explicit fem with solid-structure interaction in ABAQUS

    Thanks for the reply again. I tried what you said, and still no good results that weird behaviour still happens.I think the next step will be to try with at least 3 elements wide in the structure, just to see if it is related with any fluid (or void) leaking in or out. I do not have a big...

    Problem with explicit fem with solid-structure interaction in ABAQUS

    Yes, I am doing CEL method. About the eulerian overlapping the lagrangian I think it is done that way. In the next image you can see how I did it: https://www.dropbox.com/s/n7hz0i0hlik8is5/Eulerian_Lagrangian.PNG I know that possibly this can be done in a better way (computation wise) but I...

    Problem with explicit fem with solid-structure interaction in ABAQUS

    Hi all, This is my first post, so please don't red flag me if I am doing anything bad. I hope I can contribute to the forum in the future with the knowledge I have (mainly abaqus explicit). My problem right now is with a simulation of a tank truck, I am trying to replicate an experiment and...
