It sounds like you are using CFD-Post for your post-processing. In that case, it is the static pressure in Fluent that is called pressure in CFX-Post.

But based upon the problem that you have, you will likely want to start working with the post-processing tools directly in Fluent. Sending transient result files to Post just results in complications. Post-processing in Fluent has really improved in the last several years, so there is little need to go elsewhere.
