Hi, 

I'm running a fluid-solid interaction (FSI) simulation. The simulation working fine but the chart Monitor is not rendering. All the writings are blurring and lines did not show on the chart. 

Any way to solve it. I'm using Ansys 2020 R1. Academic license on university computers.   

Thanks

Are you using 4k graphics?  The Ansys tools aren't set up for that level of resolution.

Hi, 
Thanks for your response. 
I don't think so. I'm using this computer for simulation remotely. I guess it's just the CPU unit without any monitor connected to it. when I run dxdiag this is what it shows under display tap.

Another issue with this PC is most of the time the simulation stops unexpectedly without showing any error in Ansys and the CPU usage drops from 60% down to 1% after a few hours of running the simulation. and as you can see this PC has 32 cores and 32 processors, whenever I ran the simulation it shows in another window that only 10 cores requested no matter how many cores or processors I assign for the job its always 10.
While when I run the same simulation on another PC ( 80 processors and 40 cores) it shows me 16 cores requested and It works much faster than the 32 core PC. The license is the same ( Ansys Academic Research). 

Thanks

So this chart is supposed to show real-time data during the solve ?

How do you submit the jobs to solve ? Do you use RSM or you use some remote tool (e.g., remote desktop) to connect to the machine, then solve it locally there ? and is it solved in foreground ?

Yes, it shows real-time data. 
I don't use RSM. I use remote desktop connection and solve it locally in the foreground.

Let's focus on the plotting issue first.

As Rob's noted, there may be an issue with 4k monitor. Can you try reducing the resolution to be 1920x1080 and see if that makes a difference ?
