Thanks for voicing this and I will apologize for the lack of response on our end/delay. In the past we have only offered certificates for those who have successfully completed the Workshops. However, we have been receiving more and more requests for certificates for the Professional Training and will begin to distribute these as well.
We are working on the certificate templates right now (for the CFD and FEA, respectively). So just a little more patience and it'll be on the way!
