Hi all,

Is there a Lumerical script command to output the memory requirements from the 'Check" toolbar option for FDTD? I tried looking on the Lumerical Scripting webpages and this forum and couldn't see any information on this. Thanks!

Yes, in 2021R2.1 new release you can use runsystemcheck and then you will get a struct, which has sub-struct containing memory check information.
For example:
?aa=runsystemcheck;
Struct with fields:
Approximate_Memory_Requirements
Frequency_WaveLength_Settings
Materials
Memory_Details
Memory_Recommended
Mesh_Override
Total_FDTD_Yee_Nodes
then you can get the memory info:
?bb=aa.Approximate_Memory_Requirements;
Struct with fields:
Alert
Data_Collection_Bytes
FSP_Saved_Monitor_Data_Bytes
Initialization_and_Mesh_Bytes
Running_Simulation_Bytes
Here is the initialization and mesh memory:
?bb.Initialization_and_Mesh_Bytes;
result:
167772160
Please update to the newest version.
