No,I will try your solution tomorrow because I'm out of office.And thanks for your reply again.By the way,I sent a email to support@coade.com as same question.
Another question is:Refer to water hammer spetrum analysis,the cutoff frequency is about 300Hz for many times,this is suggestion of ceasar's dynamic manual,but for steam hammer,which cutoff frequency should be selected?We use pipenet to calculate hammer force,and input to Ceasar to generate the spetrum,and we find the biggest DLF's value is 30Hz(just example),if we select 30Hz or maybe little more than 30Hz,so is it enough to consider the system's safty when steam hammer happen?If not,and we must select 300Hz as cutoff frequency,but our system is too flexible,what can we do?
Thanks for your relpy!
Best regards!
