    LS-DYNA Mitral Valve Modeling Help

    There is a bunch of great information on the Living Heart Project which is done in Abaqus however I suspect that some of the techniques can be transfered to LS-DYNA. https://www.3ds.com/products-services/simulia/solutions/life-sciences/the-living-heart-project I hope this helps. Rob Rob...

    How to mesh this structure?

    On first inspection why are you not using shells? Aside from that here are the steps that I used to create the mesh below and attached. 1. Converted to independent parts in the assembly. To make it easier to change them all at once 2. For the face panels I used a local seed of 3 elements...

    Low memory problem

    Have you tried to run on a fresh reboot with nothing else running? It sounds like you might have something else that's a memory leak. While running keep track of the task manager periodically. Did you check out the DAT, MSG and STA files also? I hope this helps. Rob Rob Stupplebeen Rob's...

    Learning ABAQUS

    Hi Ahmad, I own a reseller of Abaqus among other Dassault products based in the US. I can confirm that the Simulia training is a very good option if you can afford it both in term of cost and usually more importantly, being away from the office for a week. Most of my customers take a...

    Abaqus 2016 installation error

    Unfortunately the Zip file wouldn't download. It could also be that the installation files are nested too deep. Try placing the install files in something like C:\temp then install into the default locations. I hope this helps. Rob Rob Stupplebeen Rob's Engineering Blog Rob's LinkedIn Profile

    Abaqus 2016 installation error

    I searched the knowledge base: "The installation can fail with this error message if any files in the installation package extend over 260 characters including the file path." Basically install to a shorter root directory. Are you changing from the defaults? I also created a blog on how to...

    Create Instance with different materials without using TIE Constraint

    I'm using Abaqus 2016 so I have uploaded the INP file instead. Here are the steps that I did. 1. Deleted merged solid and emptied the assembly. 2. Added both solids to the assembly. 3. Translated the inclusion 1 unit down. 4. Merged instances deleting the original and retaining the boundaries...

    abaqus simulation

    This is certainly a unique simulation! I would look into Abaqus/Explicit possibly using CEL technology. You may be able to skip CEL using a yield stress. Unfortunately, your Catia Product did not include the Parts so it's an empty assembly with broken links. I hope this helps. Rob...

    Create Instance with different materials without using TIE Constraint

    I made the change to line 49 but it has an error saying that the IGS is corrupt. I did import the IGS by hand without issue though. On your CAE file can you try compressing the MDB? Also, deleting the mesh then compressing may make it small enough. By the way what is this? The IGS looks very...

    Create Instance with different materials without using TIE Constraint

    Can you share your CAE file? Did you create the constraints before merging? They may have been carried over as intelligent as Abaqus can when you merged. Imagine if you have a fixed face then merge 2 parts the face should probably still be fixed. I hope this helps. Rob Rob Stupplebeen Rob's...

    Problem with Helix and elliptic cross-section

    Can you share your CAE file? In general I usually suggest using a CAD program to create anything but basic geometry. This would be fairly easy in SolidWorks or Catia. I hope this helps. Rob Rob Stupplebeen Rob's Engineering Blog Rob's LinkedIn Profile

    Best Practice - FEA Methodology

    Under the project name I create a folder named FEA which houses all the inputs, outputs etc I also create a CAD folder and others as well. I agree with gravityandinertia to keep a document open and take notes real time. I personally use PowerPoints because just about every useful simulation gets...

    Abaqus Parallel Execution to Maximize Throughput

    You spurred me on to create a batch file that I've been planning to do. Basically edit the file in a text editor and it will report the clock time between solves with different CPU and GPU options. I didn't do anything fancy like loops or anything. Just dump the results into Excel to see how the...
