PEP-X is a proposed future X-ray light source. In designing PEP-X short range wakefield due to 0.5mm bunches need to be evaluated in an 300 meter long Undulator Taper structure as shown below.
Wakefields of Undulator Taper with a 0.5mm bunch is calculated with 6000 cores and 12 hours. It used 0.25 mm mesh element size with 19 million quadratic tetrahedral elements for the whole geometry.
