Hello,<\/p>\n

A problem occurred when we needed to simulate an electromagnetism problem with FEM-BEM; we needed to simulate magnetic pulse welding. The magnetic pulse welding process is shown in Figure 1\u3002 We want to simulate the deformation process of the flyer plate using Dyna simulation.<\/p>\n

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

Figure 1<\/p>\n

I could get the simulation results perfectly when my flyplate was just aluminium as shown in figure 2.<\/p>\n

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

 <\/p>\n

However, when I add aluminum foil to the aluminum plate, as shown in Figure 3, the dyna does not give me any results or will not converge.<\/p>\n

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

Figure 3<\/p>\n

Why is Dyna not able to calculate the results? We desperately need to simulate the deformation of aluminum plates and foils; <\/p>\n

Using R15 MPP double precision.<\/p>\n

Please help me.<\/p>\n

Regards<\/p>\n
