AMESim仿真

在做 AMESim 仿真过程中，Warnings/Errors显示Dissipation number, Dn = 1.82561e-005, indicates that viscous effects are too small for this submodel.
Consider
using a HL041 (with nodes = 0 and nfdf = 0) submodel.
Warning in HL02 instance 1.
Dissipation number, Dn = 0.000338295, indicates that viscous effects are too small for this submodel.
Consider using a HL041 (with nodes = 0 and nfdf = 0) submodel.
Warning in HL02 instance 2.
Be careful! the flow area is limited by
(PI/4)*(dspool^2-drod^2) and not by xmax.
Warning in BRP025 instance 1.
Warning in BHC11 instance 2
Chamber volume is limited by vo
l0 / 100 = 0.000000.
模型图如下：但是仿真还能继续，请高手指点，先谢谢了！

你的容腔dead volume 初值设置的不对。Warning in BRP025 instance 1.
Warning in BHC11 instance 2  这两句。。为了保证仿真继续。amesim限定了容腔的最小体积，为了让它不是零。

第一个warning不太清楚。

没有溢流阀做安全保障呢?
