I have a business lumerical MODE floating license and I would like to run a parameter sweep within Lumerical. If I run the sweep, I receive license error: Unable to checkout the requested HPC license. This operation requires 1 licenses for feature fde_engine.

Why can't I run a param sweep? Is there a wrong setting or am a missing a license? Single mode calculations run without issues.

@fabian.zschocke,

How are you running the sweeps? Are you running this from the CAD/GUI? Can you share screenshot of your resource configuration? Or the command used to run the sweeps?

[fabian.zschocke]

Is it possible to run a parameter sweep from GUI with lumerical MODE floating license? Is HPC license included? Please advice which resource configuration to use. Is local host correct?

@Lito Yap

Since I have a business license, please send an E-Mail adresse where I can post my question and attach a screenshot. Thx

I am running the sweep directly out of lumerical:

Using the following configuration:

Unfortunately I cannot share a screenshot. It says: local host, local host status success.

@Fabian, 

(1) Based on your support registration, you are using the Ansys Lumerical Academic Teaching License (25 tasks). 

(2) Business or Commerical license users can register for commerical support with Lumerical as shown in our KB: > https://optics.ansys.com/hc/en-us/articles/5609426062483. Where commerical license users can submit/open a ticket in the Lumerical support portal > https://optics.ansys.com/hc/en-us. 

(3) Yes, you can run parameter sweeps on Lumerical including MODE (EME/FDE/varFDTD). You should have 25 MODE FDE solver licenses. You can set your resource configuration to run using the available cores on your machine. See the following KB articles for details:
>https://optics.ansys.com/hc/en-us/articles/360025161033-Compute-resource-configuration-use-cases,
>https://optics.ansys.com/hc/en-us/articles/360058790674-Resource-configuration-elements-and-controls 

You can run concurrent parametric sweeps on your local PC or remotely as shown here: >https://optics.ansys.com/hc/en-us/articles/360026162414 

(4) Ensure that you are accessing the license server with available licenses. Check the license status and availabity as shown in this page: >https://optics.ansys.com/hc/en-us/articles/5770622400659

Dear @Lito Yap

thank you for your feedback. I follwed your instructions. I could not register my business license for support (did not receive confirmation E-Mail).

Checking license status shows:

ansyslmd: UP v11.17.2
Feature usage info:

Users of lum_eme_solve:  (Total of 1 license issued;  Total of 0 licenses in use)

Users of lum_fde_solve:  (Total of 1 license issued;  Total of 0 licenses in use)

Users of lum_varfdtd_solve:  (Total of 1 license issued;  Total of 0 licenses in use)

However already the first sweep job fails:

As mentioned in my previous reply, you are currently using/accessing the Ansys Lumerical Academic Teaching License (25 tasks). 

If your company bought Lumerical Commercial entitlements, configure Lumerical to obtain the license from your company's license server and not from the Academic Teaching licenses that you are currently using/accecssing. Then register for support while accessing the commercial licenses from your company's license server as shown in our KB guide here. 

Let me know if you have any questions or run into any issues. 

[fabian.zschocke]

Unfortunately your mentioned instructions do not work, but I was able to get commercial support anyway. Turns out there is a bug in the Lumerical SW.

[Lito]

@fabian.zschocke,

We now have you registered for commercial support under your company's license/entitlement. Support registration is associated to the license/entitlement that you are using. I believe, your previous support registration was done while you were accessing/obtaining the licenses from your university's license server. 

For the run time or licensing error - that is an issue with the previous version of Lumerical that is not related to the support registration.
