<p>Hello everyone,<\/p><p>I have been trying to run a .wbpj file on my University’s Linux-based HPC using Ansys 2024 R1, but unable to do so due to an error. Even when I submit an empty “minimal_test.wbpj” file, it returns the following error. The error is the same regardless of whether the .wbpj file is my actual simulation setup (on Ansys Polyflow) or just an empty file for testing purposes.<br><br>I am attaching all relevant files for you to check. I use a SLURM script to run it on my University’s HPC cluster.<\/p><p>Error file:<\/p><p>_____<\/p><p>_____<\/p><div>Job started at: Fri 23 May 12:39:25 BST 2025<\/div><div>SLURM_JOB_ID: 7752<\/div><div>Attempting to run Workbench…<\/div><div> <\/div><div>Framework error caught :<\/div><div> <\/div><div>Fatal error: An unexpected error has occurred: Unable to load project ‘\/home\/postgrads\/2913170B\/DieSwell_Simple\/minimal_test.wbpj’: Ansys.Core.Events.EventPublishFailedException: Failed to create object 6a7e2939-5ffe-47a0-bda7-fb034a0e3a0f, error code hres: 8000FFFF —> Ansys.Core.Events.EventPublishFailedException: Failed to create object 6a7e2939-5ffe-47a0-bda7-fb034a0e3a0f, error code hres: 8000FFFF —> Ansys.Core.Events.EventPublishFailedException: Failed to create object 6a7e2939-5ffe-47a0-bda7-fb034a0e3a0f, error code hres: 8000FFFF —> Ansys.Core.Events.EventPublishFailedException: Failed to create object 6a7e2939-5ffe-47a0-bda7-fb034a0e3a0f, error code hres: 8000FFFF —> System.Runtime.InteropServices.COMException: Failed to create object 6a7e2939-5ffe-47a0-bda7-fb034a0e3a0f, error code hres: 8000FFFF<\/div><div>  at Ans.ComponentSystem.Interop.MiniCom.AnsCoCreateInstance (System.Type classType, System.IntPtr aggr) [0x0007f] in <44fa2ffd3745466592ae7a1a4b470645>:0 <\/div><div>  at Ansys.ACT.Interop.DefinitionIdentifier.ClassFactoryCreateObjectDelegate (System.IntPtr aggr) [0x00000] in <90c9343f97d04f79bbc2eb7d1584c740>:0 <\/div><div>  at System.__ComObject.CreateIUnknown (System.Type t) [0x00015] in <e85874d36dd54c51a7dcd93d72f2c404>:0 <\/div><div>  at Mono.Interop.ComInteropProxy.CreateProxy (System.Type t) [0x00000] in <e85874d36dd54c51a7dcd93d72f2c404>:0 <\/div><div>  at System.Runtime.Remoting.RemotingServices.CreateClientProxyForComInterop (System.Type type) [0x00000] in <e85874d36dd54c51a7dcd93d72f2c404>:0 <\/div><div>  at System.Runtime.Remoting.Activation.ActivationServices.CreateProxyForType (System.Type type) [0x0003b] in <e85874d36dd54c51a7dcd93d72f2c404>:0 <\/div><div>  at (wrapper managed-to-native) System.Object.__icall_wrapper_ves_icall_object_new_specific(intptr)<\/div><div>  at Ansys.ACT.WorkBench.EventObserver.Receive (Ansys.Core.Events.IEvent eventInfo) [0x0029d] in <a550bec809dd4257963b4da898234bfe>:0 <\/div><div>  at Ansys.Core.Events.EventObserverProxy.Receive (Ansys.Core.Events.IEvent eventInfo) [0x00000] in <2269a6352d194a2cb2dedbf711bef8d1>:0 <\/div><div>  at Ansys.Core.Events.EventInvoker.Invoke () [0x001a8] in <2269a6352d194a2cb2dedbf711bef8d1>:0 <\/div><div>   — End of inner exception stack trace —<\/div><div>  at Ansys.Core.Events.EventInvoker.Invoke () [0x00213] in <2269a6352d194a2cb2dedbf711bef8d1>:0 <\/div><div>  at Ansys.Core.Events.EventPublishHelper+<>c.<FireAsyncWait>b__8_0 (System.Object obj) [0x00000] in <2269a6352d194a2cb2dedbf711bef8d1>:0 <\/div><div>  at Ansys.Core.Events.ThreadPoolWait.HandleWorkItem (System.Object state) [0x00007] in <2269a6352d194a2cb2dedbf711bef8d1>:0 <\/div><div>   — End of inner exception stack trace —<\/div><div>  at Ansys.Core.Events.ThreadPoolWait.RethrowExceptions () [0x00051] in <2269a6352d194a2cb2dedbf711bef8d1>:0 <\/div><div>  at Ansys.Core.Events.ThreadPoolWait.WaitOne (System.Int32 millisecondsTimeout, System.Boolean exitContext) [0x00076] in <2269a6352d194a2cb2dedbf711bef8d1>:0 <\/div><div>  at Ansys.Core.Events.ThreadPoolWait.WaitOne () [0x00000] in <2269a6352d194a2cb2dedbf711bef8d1>:0 <\/div><div>  at Ansys.Core.Events.EventPublishHelper.FireAsyncWait (System.Collections.Generic.List1[T] events) [0x0006d] in <2269a6352d194a2cb2dedbf711bef8d1>:0&nbsp;<\/div><div>&nbsp;
