    Centroid of named selection (face) with APDL

    Hi, I'm trying to get the centroid of a named selection using APDL. The named selection can have arbitrary shape, and needs to be found for the deformed shape (at least when large deflection is activated). I've tried the following code: cmsel,s,NamedSelection asum *get,CentroidX,area,0,cent,x...

    Rigid Dynamics

    Hi, I'm trying to do a rigid dynamics simulation to investigate how some cargo react to ship motion during transport. I've created a simple model as seen below [Figure 1]. Figure 1: Model nomenclature I have two parts that are connected with a bearing. The "blue" part (Stationary part) will...

    RSM setup

    Hi, I'm trying to setup RSM (2019R3), by following this guide. Everything seems fine, and I'm able run the test in the RSM configurator on my local machine successfully. Trying to submit a job from Mechanical though fails with the message: "An error occurred while starting the solver...

    Get forces and moments from connection using APDL

    Hi Jason, Thanks. It was very good. I've done the setup exactly as you show, but I'm not able to reference the cid by the name created in the command at the contact (BB_1_1). I know the my value is very small, but there's a relative difference of >200%. I see similar varying accuracy in the...

    Get forces and moments from connection using APDL

    Hi Jason (and anyone else for that matter) I'm hoping you're still following my thread and are willing to help. I'm back from vacation and finally had some time to look at the problem again. I've tried the code you supplied again, but instead of using the definition from the command block at...

    Get forces and moments from connection using APDL

    Hi Jason, I've got the command block at the contact. I've tried simplifying my solution code, but am still unable to get the ESEL command to work. Keep getting the warning: Specified range of 0 to 0 is not permitted. The ESEL command is ignored. I've even tried making a new command block only...

    Get forces and moments from connection using APDL

    Hi Jason Thanks for your guidance. I've had some time to look at things further, but am still having some trouble. The underscore before cid was taken from a script that someone else have made, that does something similar to what I want. I haven't been able to find out if it makes a difference...

    Get forces and moments from connection using APDL

    Hi Is it possible to extract force and moment reactions from contacts using APDL? First I need to say that I'm new to APDL, and only have basic knowledge of other programming languages. Here's a more descriptive explanation of what I'm trying to achieve and what I've done so far (no final...

    Continue simulation in new system

    Thank you very much for the links L K. Too bad there isn't a more simple way, where you don't have to read in the results from the previous load steps. I would really like the ability to add load cases later on, so I guess this is not a viable solution in my case. The text in the first link...

    Continue simulation in new system

    Hi Is it possible to continue a simulation in a new system. I know you can do sub-modelling, but what I "simply" want to achieve is instead of having say four load steps in one simulation, I want the first two in one system and the last two in a second system. I have several simulations that...

    Tangency in surface loft

    Hi I'm trying to create a surface loft (the image below shows the loft without the existing geometry). I've almost made it work now, but am still having some trouble. When trying to merge my loft with the existing geometry, there are a lot of small gaps and one too large for the knit future...

    Simulation of water cooling circuit

    The problem have been somewhat solved. See solution in http://ole.dixib.dk/indledende_beregninger_w.m. There's still some problems in though. Weird things happen when I change the starting temperature. Haven't been able to find a solution to this problem. For now the above version have been...

    Simulation of water cooling circuit

    Hi I'm working on a water cooling circuit, where I have a heat tank with a heat source that's on/off in 5 min. intervals, and a buffer tank, that's constantly cooled by a heat exchanger. There's a pump, that cycles water between the two tanks to keep a temperature of 15 °C (+/- 0.5 °C) in the...

    Rotation around axis/construction line

    No, I haven't tried. But I know it won't work, since I don't want the room to spin around. Besides the parts are not centered in the view, which they will be with the suggested solution. I've ended up letting the part be stationary.

    Rotation around axis/construction line

    Thanks for the advice, but it won't work in the given situation. The animation is happening inside a room, where the parts are placed on a table. From there they are moved up in front of the camera, where I wish for them to rotate (one by one). Rotating the camera in this situation would make...

    Rotation around axis/construction line

    Hi Haven't been able to find anything about this. Is it possible to (in an animation) to rotate a part around an axis (reference geometry) or a (construction) line in a sketch? Thanks in advance dixib

    Problem with circular pattern

    Thanks for all the links and suggestions. I'll look into it as soon as I get the time for it.

    Problem with circular pattern

    Haven't heard the term body in SW before. I'm used to working with bodies in Catia (and miss the boolean features in SW). Do you know af any ressource to explain the body system in SW, since I don't quite understand why some things are suddenly considered bodies? The way you propose to do...

    Problem with circular pattern

    Thank you very much for looking at it. I'd prefer if was able to do my pattern outside the sketch, since I feel it gives a better structure of the file and simplifies the sketches for later editing. Yes, it's a 2009 file. And you're right, I'd enjoy it much more, if I make it myself :D Think...

    Problem with circular pattern

    I've never worked with the sheet metal tools, so I don't know how to use them. Maybe I just need to find some tutorials and get into it...? I've tried mirroring the features too, but get the same error message. The part is not a production part, but just a modelling exercise I've given myself...
