Re: Adding a Thermally Active Bedrock Body to a Prognostic Flowline Model

Thank you so much! That worked like a charm. I used the "Mapping Mask Name" as in test case structmap7. I have attached the updated sif for anyone who is curious.

I appreciate your help!

Re: Adding a Thermally Active Bedrock Body to a Prognostic Flowline Model

Hi, I spent some time trying to get to get a mask for the structured mesh mapper to work, using something like Exported Variable i = string "material:ice" but it was not really clear to me to what extent I needed to do this. As a result I kept running into the error " StructuredMeshMa...

Re: Adding a Thermally Active Bedrock Body to a Prognostic Flowline Model

Hi,

I do not need a temperature jump. I will work on adding a mask to structured mesh mapper.

Thanks!

Adding a Thermally Active Bedrock Body to a Prognostic Flowline Model

Hi all, I hope everyone is doing well and staying healthy. I would like to add a thermally active bedrock body to a prognostic flowline model. If you start with the toy glacier example given in the elmer/ice courses is there a relatively straightforward way to do this? The reason I ask is that I am ...

Re: getFrictionLoads User Function resulting in segmentation fault error

Thanks for the help! The simulation works fine without the third body for the bed now.

Re: getFrictionLoads User Function resulting in segmentation fault error

Hi all again, just posting to say that I appear to have resolved the problem. I made the bed a separate body as was done in the test friction heating test. If anyone has any thoughts into why this makes a difference I would be interested to hear.

Thanks!

Re: getFrictionLoads User Function resulting in segmentation fault error

I just thought I'd post an update now that I've spent some more time on this issue. I ran the FrictionHeat test in elmerice/Tests, and I found that the frictional load user function works fine. I then ran the ArucoElmer Ice flow and temperature coupling example from the 2016 online course. This exam...

Re: Spiky Ice Sheet Surface in transient flow line model

Thanks again for all of the help. It does appear that trying to enforce a no slip boundary condition was making the problem worse. The simulations seem to run better if there is some amount of sliding allowed near the terminus.

getFrictionLoads User Function resulting in segmentation fault error

Hi all, I was working on adding frictional heating into a 2D transient ice sheet model, and when I try to evaluate the "getFrictionLoads" User function, I get thrown this error. In other words, the simulation runs fine until I attempt a model run with this additional function. TemperateIce...

Re: Spiky Ice Sheet Surface in transient flow line model

Thanks for the timely replies. I hadn't thought about higher order elements, and I will look into that. I had reduced the time step by a factor of ten (to a tenth of a year) previously, and had no success in disappearance of the spiky surface. I will try to reduce it further to see if that helps as ...
