Hi All,
I'm trying to simulate a simple solenoid (Something like a verification of biot-savart law) with N turns etc. The purpose is to measure H inside the device.
The problem :
-----------------
I'm getting the following msg :
======================================================================
Solver cycle: 1
======================================================================
Stimulation at discrete port 1
--------------------------------------------------------------------------------
Units settings:
Dimensions: cm
Frequency: MHz
Time: s
--------------------------------------------------------------------------------
Mesh summary:
< 0.5 :0.6 %
< 0.25 :0.4 %
< 0.1 :0.1 %
< 0.05 :0.0 %
< 0.02 :0.0 %
Minimal filling: 3.201 %
--------------------------------------------------------------------------------
*** Error ***
The current settings will lead to an extremely long simulation time.
You may improve the simulation speed by:
1. checking the frequency range and units settings
2. extending the simulation frequency range
3. checking the mesh to avoid very small mesh steps
--------------------------------------------------------------------------------
The means i've taken :
a. I've arranged a reasonable mesh (honestly)
b. The frequency bandwidth is 400% of what should be according to the signal's FFT.
c. as you can c in the units, i'm simulating a large one - ~60cm diameter.
The result :
Simulation time is tooooooooooooo long !
the timestep is (ns*1e-6).... I need Help !
(BTW: It would b nice if someone has a solenoid model to spare... )
Desperatly,
P.
