Hello,<\/p>\n

I have a python script which sequentially does the following with an FDTD session (called fdtd here), using lumapi:<\/p>\n

    \n
  1. Load in a previously defined GDS file into the Lumerical session (creates an imported geometry). <\/li>\n
  2. Sets the material properties of the imported geometry to the desired values (using fdtd.set).<\/li>\n
  3. Saves index monitor outputs to a matrix object "data_set" in the script workplace (i.e. saves permittivities as a function of x, y, z, f, etc.)<\/li>\n
  4. Retrieves the index monitor outputs from the Lumerical script workplace, into the python script (using lumapi.getVar(fdtd.handle, "data_set"))<\/li>\n<\/ol>\n

    This works most of the time and gives me the correct results. However, on occasion, the first time I poll for "data_set", I get the permittivity values PRIOR to the material properties being updated (i.e. the same results as if I had omitted step 2). I then have to execute steps 3 & 4 again to get the correct results.<\/p>\n

    I suspect that this is because the lumapi functions will return prior to the scripting functions completing in Lumerical. I'm looking for some way to block my python script before step 3, until step 2 has completed. Is this functionality provided anywhere in lumapi?<\/p>\n

    <\/p>\n<\/p>\n

    Thank you! Any suggestions are much appreciated.<\/p>\n","protected":false},"template":"","class_list":["post-160746","topic","type-topic","status-closed","hentry","topic-tag-python"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
