使用PASSKEy2的过程中,模型使用Power_source =1 直接从voltage.input中读取时,可以正常运行,一旦开启Power_source=2 耦合外电路自洽求解电极电压时就会出问题。
有大佬遇到过这种问题吗?
错误开始时,控制台输出: DVODPK-  At start of problem, too much accuracy

      In above message,  R1 =                  NaN

(1)如果第一步就报错,大概率电路配置有问题,初值不自洽或给了很刁钻的参数,导致电压都NaN了;
(2)没有上传具体配置,只有一页报错提示,是没法锁定问题的。
