I am trying to create a moving block from a pressure inlet. I have set up a dynamic mesh. I do not know how to write my own udf though. Any assistance would be great. Please help.

Please take a look at the Fluent Customization manual. There are several UDF examples you can use as your starting point to write your code. Here is the link
If you are looking for instructions on how to use this help, please have a look here.
I hope this helps.

I have working udf for the movement of the zone reference for dynamic mesh. However, I would like my moving zone to stop when it contacts with the wall. I get an error when the zone reaches the wall too. I have checked 2.6.6 DEFINE_CONTACT for the details but I cannot interpret the code given. Any assistance would be appreciated. I like learning about CFD Ansys. Thank you for your help so far.
I have attached my udf and dynamic mesh motion for reference.

Please see if you can use the 'Contact Detection' feature in Fluent for this. Here are the details.
Also, as Ansys employees, we are not able to open any files attached to this community. Just an FYI.

I have visited the link but am having trouble when using it on Fluent. When i changed the proximity setting to a higher threshold, I believe contact was detected but my program has been interrupted. Every time I run it the program is interrupted and I have to close it through task manager. Thank you for you help. I believe we are almost there.
This is a picture for reference.
