Hello, I am really new to CAESES and I tried the s-duct tutorial, followed all steps but I am getting an message: External process start failure [Starting process C:/Users/HP/Desktop/skola/DP/sduct/sduct/manual_results/baseline/Runner//Allrun failed: Process failed to start:] Currently using OpenFOAM v1912 installed on Ubuntu 18.04 for Windows 10, Allrun and stdouterroroutput files are attached. I will really appreciate any help! stdouterroroutput.redirect Allrun
Hi guys, today I want to share with you my latest feature which creates a bounding box for your OpenFoam internal flow geometry. The idea came, when I struggled with SnappyHexMesh because the edges of the boundaries where not captured correctly, which resulted in a bad prismlayer mesh like this: (image 1) I found out that the reason for this, was the bounding box, where the inlet and outlet boundary do not lay within the first layer of the box like this: (image 2) So I created I bounding box which automatically adjusts with the changing geometry. It calculates the maximum and minimum positions and creates the bounding box with a user specified offset. A nice setup looks like this: (image 3) This setup produces a nice volume mesh with clean prism layers: (image 4) The complete bounding box, where the subdivision in x, y and z coordinates can be specified, looks like this: (image 5) The following picture shows how to connect the BlockMeshDict with the bounding box feature: (image 6)Remember that you have to create an entry for the vertices by selecting these, right click and select new entry: (image 7) This creates a new entry in your config dialog. There you have to change the type to FString: (image 8)Do the same for the line where the blocks are defined (see image 6).Now you have create a new entry for the point in mesh, which you can find in your SnappyHexMeshDict. Follow the same procedure, but just mark the three coordinate like this for a new entry:(image 9)That's it. This is just a first version of the feature. I could imagine to write another feature for the creation of the bounding box for external flows, where you could specify different patches within the BlockMeshDict. Of course you are also welcome to post your features here in the forum. Attached is the feature and an example how to use this feature with a complete software connector. This example by the way couples OpenFoam for Windows with CAESES. Have a nice day Carsten duct_win_forum.fdb OpenFoam_BoundingBox.fdf
Hello, This guide will show you how you can connect OpenFOAM to CAESES-FFW or any other application. Using the Software Connector, you need a executable of the Local Application. If you want to start this application with a script, do following: create on your Desktop a text file with the execution command of your desired external application (OpenFOAM) and save as 'adder' add the script 'adder' to your Input Files in the Software Connector and 'double click' it, so that it is copied into the project and is converted to a Template click on computation (in the center of the Software Connector) create a new Local Application (using the green + symbol) define the Executable: write down the name of the Template 'adder' which you have imported in the Input Files run the Computation (click on the play button) check the result in the Task Monitor (on the right side shaded widget) and click the green button in the top left corner to show the finished computations Attached is a little example which shows this. In this example the script adds the Argument of the computation (which is defined by the Variable pm1) to a defined Variable in the script (addend).
