Help 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. ...

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...

Exact 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...

Optimize 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...

Model Issues with Ascans
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...

FMC 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...

When to implement Rayleigh damping
I was wondering when to use Rayleigh damping when modelling. I am simulating Titanium grain models and have been using the following damping to my model, rdmp titan $freqdamp db 0.3 1.2 1e+06 1 0.0...

Can't find material interface
I have removed all the water boundaries around my model so it is just air boundaries around all 4 edges of the domain.I am trying to simulate a plane wave across the length of the material boundary...

Image not plotting in OnScale Correctly
I am having an issue plotting my image as it is looking very strange. I am using the same method I always use. I plot both in Matlab and Onscale and they always look like they should. This is my ma...
