CST Microwave Studio Expert Required

I am looking for an experienced CST Microwave Studio expert to help optimize and correct my CST design so that its S-parameter results closely match my HFSS simulation.

I have already designed a bandpass filter operating from 8 GHz to 16 GHz in HFSS, and the results are correct. I replicated the same design in CST, but due to port configuration / port definition issues, the CST results are not matching the HFSS response.
Your task is NOT to redesign the filter, but to:
Analyze my existing CST model
Identify issues related to ports / excitation / boundary setup
Optimize the CST port settings and simulation setup
Adjust the CST model (only where necessary)
Ensure CST S-parameters closely match HFSS results

What I Will Provide:
HFSS design file
HFSS S-parameter results
PowerPoint with full design dimensions & structure details
CST design file
Expected Outcome:
Correct CST simulation setup
Proper port configuration
CST S-parameter results matching HFSS (8–16 GHz bandpass response)

Requirements:
Strong expertise in CST Microwave Studio
Experience with microwave/RF filters
Deep understanding of port definitions, waveguide ports, lumped ports, boundaries
Ability to troubleshoot simulation mismatches
Fast turnaround (urgent project)
