David Harra commented, Hi Tapiwa. For some reason, anytime I share my strathclyde one drive OnScale can't access it. I could easily email it over to you if that is Ok?ThanksDave :)

David Harra created a post, AnsweredHelp with Model Dimensions
I am needing help to obtain specific material dimensions for a titanium homogeneous model with an array configuration.Normally I use a table file which reads in my grain data to plot the material. ...

David Harra created a post, OnScales Word Character Limitations
I am wondering if there is a way to maximise OnScales character limits. I am looking at models of grain maps and when I read in files that are around 26,000 grains I often get errors due to charact...

David Harra commented, Hi TapiwaHow would I remove the DC part of the signal and how do you compensate for the offset? Do you have any basic Matlab examples of doing this. I would really like to do this and compare these...

David Harra created a post, AnsweredExact Arrival Times from simulations
When I simulate my grain structure in OnScale.I am looking at through transmission with an array set up. I am cross correlating the input signal with the simulated signal. I then perform a Hilbert...

David Harra created a post, AnsweredOptimize Array Model
I have built an array model to inspect titanium grain structure. I was wondering if someone can help tweek some parameters.At the moment I am using 2 arrays, one on the opposite side of the materia...

David Harra commented, Hi ChloeApologies, I seem to have fixed this issue as I believe I was making a small error when I was normalising my signals. After normalising my transmission signal, I was then normalising the re...

I am wondering if anyone can help me make sense of my model. I believe my model to be set up fine, but the results seem to say different. The geometry of my model looks as below.The inspection I a...

David Harra created a post, AnsweredFMC Model Help
HiI am running an FMC model in Onscale using 32 elements using the batch control. Every time the simulation goes onto the next element OnScale has to load all the material parameters again for ev...
