Updates and test cases

Dear IPW2 Participants,

Thank you for your interest in the 2nd Ice Prediction Workshop. This letter provides an update of what to expect over the next few months.

  • IN-PERSON ONLY WORKSHOP:  At this time we are planning for an in-person-only workshop to be held on June 23, 2023 in conjunction with the SAE International Icing Conference (
  • TEST CASES: An updated document describing the test cases along with the geometries (CAD files) and structured/unstructured grids for test cases have been posted on the IPW website:
  • EXPERIMENTAL DATA: Experimental surface pressure data for the CRM65 Midspan and Inboard model cases is available on the IPW website.  Experimental surface pressure data were not acquired for the low-speeding icing RG-15 airfoil cases.  We are compiling the experimental ice shape data. The experimental results for the CRM65 model cases are taken from existing publications, so everyone should already have access to them in PDF form.
  • COMPARISON STANDARDS: The organizing committee has developed procedures for post-processing of experimental results. This document is available on the IPW website.  We are requesting that all participants utilize the provided Tecplot Python scripts for post-processing.  We are currently working with Tecplot to provide free temporary licenses to IPW-2 participants.
  • SUBMISSION DEADLINE: Participants will have until April 1, 2023 to complete their simulations and submit results for cross-comparison. The organizing committee has a group of volunteers prepared to analyze the participants’ simulation results in preparation for the workshop.
  • SURVEY: Finally, we will soon be sending out a survey to gauge the number of cases being run by all participants and which participants will need access to a Tecplot license.  The survey results will help us to plan an agenda for the workshop.

Thank you for your participation in this activity,

IPW2 Organizing Committee.
