Muliple hole diameters
I have created an LS-DYNA model with a 2D shell mesh for a plate of size 100 mm × 20 mm × 10 mm. The model has excitation nodes selected at the middle of the top edge, and there is a circular hole with a radius of 2 mm at the center of the plate. I would like to study the effect of the hole size on the excitation response…

(Flux2D) Translation Transient in Linear Induction Motor - Difficulties
Dear ones, I'm having considerable difficulty to simulate a translation transient in double primary linear induction motor with solid secondary (Flux2D). I already had some progress in "first steps", that is, electromagnetic simulation in steady state AC. All good so far. However, when I intend to take the next step -…

Replace updated CAD (only modified)
Hello, I am trying to understand Hypermeshes capability to work with CAD programs. SInce there can be some non trivial geometry chages in an FEA process, sometimes updating the original CAD is easier than hacking some surfaces in Hypermesh. Since there are patchmesing and representation capabilitys to auto regenreate…

How to extract S-Parameters for Shunt Capacitor in SimLab?
I am working in Simlab and have a very simple cylindrical "air" capacitor. It's comprised of: Outer housing with ID = 6.00 inches and a thickness of 0.125 inches Solid inner conductor with OD = 5.00 inches that's it, all suspended in air. I am able to extract s-parameters from the solution parasitic extraction, however…

Prise en compte de DOPTPRM DISCRETE | couplage FLUX - Optistruct | Optimisation topologique
Hello, I am reaching out because I am encountering an issue during my topology optimizations. To give some context, I am coupling Altair Flux with OptiStruct to perform a magneto-mechanical topology optimization. The coupling works correctly and I am able to obtain several results. However, my goal is to modify the…

How to reduce computation time in Simlab
Hi everyone, I am running a big simulation in Simlab and it takes a huge time to finish as it needs to go through several parameters to be completed. Does any of you have a suggestion on how to speed up the computation time? I already set the number of the cores to the maximum, but I still do not see a noticeable…

Understanding the “Adapt to Thin Solids” and “Adapt to Features” Options in SimSolid
Hello, I am currently studying the capabilities of SimSolid on different models, by comparing the results with those obtained from classical finite element software. However, I am not always able to obtain consistent results between the two approaches. There are some parameters that I find difficult to fully understand, in…

Best way to parametrize electric motor?
Hello, I am designing an electric motor and I am looking for the best solution to parametrize my model in order to study the effect of several geometrical lengths in my design. At the moment I am working with SolidWorks, but SimLab does not allow me to change its geometry in a parametric way. Therefore, every time I want…

Altair Extrusion Mathematical models and theory
hello! I am currently learing Altair Extrusion and would like to understand the underlying mathematical models better. Is it possible to view the equations or the detailed calculation methodology that the software uses for extrusion simulations? I am particularly interested in the mathematical approach for the extrusion…

Why is the section plane moving in visualization mode (Post) ?
I have an issue related to the visualization of a CFD analysis. When I put a section plane and animate it, it moves, instead of showing the movement "inside" of it. Such as the current movement as the time passes. Before, when I was studying an individual piece it would let me, but now I have this big cluster of pieces and…

Auto Model Regression Results on Absolute Error and Squared Error
I have inquiry on absolute error and squared error. Does this same with mean absolute error (MAE) and mean squared error (MSE)? I did read the documentation but I'm still slightly confuse. Another question is does the relative error is same as important for regression? Would be great if someone can explain these to me.…

How to retrieve GLM hidden parameters
Hi, in a project I'm using the GLM operator (based on H2O algorithm). In particular, I would like to train a Negative Binomial model and in a second step extract the theta parameter (see here for more details). I've already seen that this parameter is not reported in the result. Do you have any idea to extract it? I was…

How Does AutoML work and how to see the hyperparameter tuning?
Hello, How does AutoML work, does it always choose the same hyperparameters for each ML algorithm or does it tune based on the data in the model? Also, if I want to report the hyperparameter tuning for a paper, how can I do so after using autoML? Thank You.

DBScan clustered back-feeding
Good morning, I am new here and also in rapid miner. I am trying to do a clustering using dbscan. Currently I get the clustering I want by manually giving more or less weight to my features. But I would like to know some operator that automatically does this function. Depending on the input data, the weight that each of…

How do you generate GA chromosomes when optimizing parameters in Optimize parameters (Evolutionary)?
How do you generate GA chromosomes when optimizing parameters in Optimize parameters (Evolutionary)? I am curious about how GA generates chromosomes in the case of continuous data when parameters are specified as ranges. In case of discontinuity, it is known to be expressed in bit format of 0,1. Can you tell me how it is…

Twitter Data mining - Dates? Missing Tweets?
Hi Everyone, I have used Rapid Miner in 2018 for an exploratory project for class and was able to capture tweets about 6 months in time. I'm trying to use it to mine tweets for something less than a month ago, however, I keep only getting 8 days ago. For an example I would only get 4-12-20 or later. I also see that the…
