Hi Nkirby,
Please do the following:
1. make sure the version on your Windows is exactly the same as the Linux:
Linux: cat /home/AnsysEM/v242/Linux64/product.info
Windows: type "C:\Program Files\AnsysEM\v242\Win64\product.info"
2. On Linux, make sure the default tempdirectory is referencing a writable location - like /tmp
This is specified in file: Â /home/AnsysEM/v242/Linux64/config/default.cfg
3. On Linux, confirm solver functionallity:
mkdir ~/anstest
cd ~/anstest
cp /home/AnsysEM/v242/Linux64/schedulers/diagnostics/Projects/HFSS/OptimTee-DiscreteSweep-FineMesh.aedt  ~/anstest/OptimTee-DiscreteSweep-FineMesh.aedt
/home/AnsysEM/v242/Linux64/ansysedt -ng -monitor -useelectronicsppe=1 -distributed -machinelist list=localhost:-1:4:90% -auto -batchoptions "" -batchsolve TeeModel:Nominal:Setup1Â ~/anstest/OptimTee-DiscreteSweep-FineMesh.aedt
Examine the ~/anstest/OptimTee-DiscreteSweep-FineMesh.aedt.batchinfo/*.log  to confirm successful completion (should solve 3-5 min)
If success, clear all but the ~/anstest/OptimTee-DiscreteSweep-FineMesh.aedt
rerun with the following change:
/home/AnsysEM/v242/Linux64/ansysedt -ng -monitor -useelectronicsppe=1 -distributed -machinelist list=$(hostname):-1:4:90% -auto -batchoptions "" -batchsolve TeeModel:Nominal:Setup1Â ~/anstest/OptimTee-DiscreteSweep-FineMesh.aedt
Is this successful?
If so, make sure:
1. Passwordless SSH is enabled on Linux
2. all firewalls are disabled on both Windows and Linux (for this test)
3. both machines are on the same network
4. Open AEDT in Windows and run:
Copy "C:\Program Files\AnsysEM\v242\Win64\schedulers\diagnostics\Projects\HFSS\OptimTee-DiscreteSweep-FineMesh.aedt" to c:\temp
Open C:\temp\OptimTee-DiscreteSweep-FineMesh.aedt

Expand the project -> Analysis -> Setup1Â
rt-click on "sweep"Â and select "Analyze"
Is this successful?
If so and you require firewalls on your Windows machine - there are multiple options:
1. you could open all ports between your Windows and Linux machine
2. you could open all ephemeral ports with something like (assuming Windows Defender FW)
From Elevated CMD (rt-click and "run as admin"):
  netsh advfirewall firewall add rule name=HFSS dir=in protocol=tcp localport=49152-65535 action=allow
3. recursively add all binaries from the AnsysEM installation to your firewall exceptions
thanks
