IBS cannot be calculated after adding a certain number of wigglers.

<t>Hello～<br/>
<br/>
I've recently been trying to see the effect of damping on IBS by adding wigglers one by one to a storage ring with long straight section, and the way I've done it is by replacing elements of drifts with wigglers. I could see the emittance decreasing as the number of wigglers increased, but after adding a certain amount of wigglers, the emittance jumped.<br/>
<br/>
I don't know if this is a bug. Attached is my lattice file and calculation results, and a Jupyter Notebook file that completes the replacement and calculation. <br/>
<br/>
