- How to define a post-processing plane inside a subdomain only?
June 6, 2022 at 8:33 amFAQParticipant
In CFX, subdomains can have complicated forms and can consist of many bodies distributed in the entire domain. To create a plane in ANSYS CFD-Post, by default, it is impossible to select subdomains only. Moreover, the “inside” CEL function is not available in CFD-Post and using the “step” CEL function may be very cumbersome. So, this is a workaround to create a plane in a subdomain only:
1. Creating a new Additional Variable in ANSYS CFX-Pre, before the calculation: – Variable Type=Unspecified – Tensor Type = Scalar – In the domain, selecting Option = “Algebraic Equation”, and Value = the equation “inside()@subdomain”. This variable defines the limits of the subdomain, with a value = 1 inside the subdomain, 0 elsewhere.
2. Running the calculation
3. In CFD-Post, creating the wanted Plane in the whole domain.
4. Then Creating an Iso-Clip on this Plane, with a Visibility Parameter set with the previously created Additional Variable with a value >=1. ->In this way, the Iso-Clip shows the Plane in the Subdomain only.
