        Hi, everyone:
</div>
<div style="font-family:"lucida Grande", Verdana, "Microsoft YaHei";font-size:14px;white-space:normal;background-color:#FFFFFF;">

<div style="font-family:"lucida Grande", Verdana, "Microsoft YaHei";font-size:14px;white-space:normal;background-color:#FFFFFF;">
        My simulation is using one laser beam irradiate on a spherical shell, and this laser beam have a 45 degree angle to x-axis. I used the cylindrical geometry, and from the output hdf5 files, I found that the intensity of laser is not symmetrically on the surface of the shell. But when i used the cartesian geometry with same 45 degree incident laser, the intensity on the shell is uniform and symmetrically.

        I guess here are some problems when i'm seting up the laser beam. My laser setup in the .par file is as follows:

<div style="font-family:"lucida Grande", Verdana, "Microsoft YaHei";font-size:14px;white-space:normal;background-color:#FFFFFF;">
        And in mesh parameters:

        So, what should i do to let the intensity of the laser on the shell to be symmetrically to the 45 degree incident axis?
