energy error too large

energy error is a warning. it is telling you that the total energy in the problem is unbalanced. the message is issued when the balance is off by 5%. this could be a result of elements eroded, element sizes not small enough, loss of materials through boundaries if using Euler and other similar symptoms. if you just want to get the problem to run you can increase the energy error tolerance or disable it by using a large cycle number for the reference energy.

总的来说,要想接着算,改大controls 里的 energy ref. cycle就可以算了,但是可能会牺牲准确度
