I am testing example of the Magnus Effect for OpenFoam-9 https://drive.google.com/file/d/1J2rKIRU8DAZadORyjUfd6OBBcfR-9rLo/view?usp=sharing

What I got from https://holzmann-cfd.com/community/training-cases/magnus-effect

And it works fine:

But when I change STL object with shifted a little position in STL file then simulation is breaking

I'm trying to write a demo server/client program in C++. I first ran my server program on my Macbook, with ngrok on and forwarding a public address on the Internet to a local address on my machine. I'm seeing something that I don't understand when I try to run my client program to connect to the server:

1. If the client tries to connect to localhost at the local port defined in the server program, the server accepts as expected and the client successfully connects,
2. If the client tries to connect to the ngrok server address at port 80 (default for ngrok), then the client connects, but the server is still blocked at the accept call. (This I don't understand!)
3. If I send an HTTP GET request to the ngrok server address, the server successfully accepts the connection.

Why do I see these? In the ideal case, I want my server to accept connections from my client program, not just respond to the HTTP GET request.

Here's my code if that helps: For the client,

I have an HTML table where some of the cells have very long text, I'm therefore trying to truncate them to a limited number of characters and add an ellipsis if they exceed it. To make the table more interactive I'm using datatables, so I tried to follow this datatables specific solution which uses their rendering features however it doesn't truncate values in my table. The example table where this isn't working can be found in this JS Fiddle.

I am learning OpenFOAM step by step, and am currently trying to create a very simple mesh with the blockMesh tool, but keep getting a floating point exception. My blockMeshDict is written in almost exact correspondence to the meshing tutorial in the section 4.3.1 of the OF user manual:

I have the following List of data.

I'm trying to do a parametric study in Ansys fluent through python. The idea is to calculate some parameters before feeding them to fluent as boundary conditions and initial conditions.

I have searched wide and far but could not come into any pertinent information... maybe i'm not looking with the good keywords.

Or is there an equivalent of ANSYS Parametric Design Language (APDL) for fluent ? I can only find information for mechanical.

Do anyone could guide me in the good direction or somewhere to go look for more information.

P.S. I could not find any information in CFD-online, ansys site or here in stack overflow.

I have 2 dataframes df1

I work on the server side Socket (use Telnet client) in Linux. Client is required to input a line in certain format: (1)command(GET/PUT/DEL), (2)key and (3)associated value (spaces to seperate in between). This key-value pair is later passed accordingly to the function(GET/PUT/DEL), which saves the data in the shared memory (keyValueStore).

I try to spilt the input into 3 parts, but there are wierd result in reading Token(2).

• may I know the reason? any advices on how to change my code? (what i expected are key1, key2 )

Thanks!
