    FEM modelling of fillet welds, effect of chamfer/penetration

    Just wanted to post here also: https://www.eng-tips.com/viewthread.cfm?qid=467201

    FEM modelling of fillet welds, effect of chamfer/penetration

    I am using finite elements to model a frame which has several fillet welded joints. I am using effective notch stress method to get accurate stresses. I studied the effect of adding a chamfer to the connected plates (butt weld and fillet weld on top). In some joints the weld toe stress reduces...

    Necessary to validate the welding strength of every joint in a large steel frame?

    You should be able to decide the critical joints from stress distribution plot of the nominal load case(s).

    Explicit meshing - what to do with sharp corners

    You should only model those radii that really matter (you want to know exact stress in that region). If even this makes the runtime unreasonable, you could use mass scaling for those small elements.

    Spaceclaim - 2D sketching

    I just tested it, should be there in the general tab. You cannot select it before selecting an entity and the direction.

    Spaceclaim - 2D sketching

    Could you post a picture of the sketch? I would just use the ruler tool to set distances between entities. I have to mention that I do not sketch a lot with SCDM. You use ruler tool by selecting for example a line in sketch, then it should be available in General tab. I believe it becomes...

    Spaceclaim - 2D sketching

    You can use project to sketch tool to project edges/points/etc from 3d body to a sketch. You also should be able to revolve or sweep instead of pulling.

    spaceclaim custom shortcut

    You can also select a face or an edge and right-click to suppress the body that they are part of.

    Have you modified the script using for example Selection.GetActive() ?

    Isn't this a thing in the newest version 2019 R3 when writing to command object?

    Define heat transfer coefficient as function

    An example what you can do in parameters section:

    Define heat transfer coefficient as function

    Share some pictures, it will make this a lot easier.

    Define heat transfer coefficient as function

    You should be able to define parameters as a function of other parameters in Workbench in the parameters page.

    What does the FEA process look like at your company?

    One practical tip, which was already mentioned is to start with fully linear model. Make sure the model is working, reaction loads etc. Then move to non-linear analysis but try to save elements. Make sure the model is working, for example in ANSYS you can visualize all the contacts at same...

    LINK11 results (WB)

    I edited the original post to show the location of the code lines in the tree structure. Is there something funky? It seems to be working as expected not taking into account the actuator force table. Your suggestion seems to be working,thanks!

    Problem exporting ARRAY values to txt file

    What do you mean by easier? Here are two different ways to write an array which has 15 rows and 1 column to a file. The contents of the code have to be in txt file which is run from apdl. The first command mwrite is more general. It can write an array which has more columns than one to a file...
