Problem occuring Dynamic simulation?

03 May 2020 0 8K Report

When my feed mixture of vapour fraction nearly 0.46 and at temperature 120°C and pressure of 603kPa, is heated to 320°C which is the temperature required for reaction, the vapour fraction becomes 1 and pressure increases to a value of 2722kPa. But when I switch from static to dynamic mode, the molar flow and temperature changes into negative value. How can I overcome this problem?
