写一封英文邮件给Jussi S. Heinonen博士，主题是关于使用Magma Chamber Simulator (MCS)软件的疑问。正文要提到目的是为了重现Adams et al.，2021NC的文章里的Supplementary

Dear Dr. Jussi S. Heinonen, I am writing to you with some questions regarding the use of Magma Chamber Simulator (MCS) software. My purpose is to reproduce Supplementary Figure 7 from Adams et al., 2021NC, where the authors first simulated the partial melting behavior of subducted mantle using the pMELTS model and then used the resulting melt for fractional crystallization simulation. I have a few questions: Firstly, while MCS can call the pMELTS model, does the fact that MCS defaults to simulating temperature decrease mean that it cannot simulate partial melting in the mantle? Secondly, when attempting to run an FC simulation using MCS, I encountered an error message stating "Type mismatch (Error 13)" after running for some time, such as at step 48. I would greatly appreciate any advice or guidance you could provide on these issues. Thank you very much for your time and attention. Best regards, [Your Name]
