前两天在user guide中看到,应该在using the solver那一章中。具体还要自己查一下。
在3D模型下模拟瞬态燃烧,湍流模型采用的是LES-Smagorinsky Lilly,燃烧模型采用EDC,通过ISAT方法加速。问题时这样的:我在初始时刻patch高温区点火,但是在刚开始迭代的几步,就提示“time step reduced in xxx cells due to excessive temperature change”,我本以为是燃烧开始温度变化较大,但迭代几步...
time step ..time step reduced in 4 cells due to excessive temperature changeFLUENT开始计算的时候出现这个,请问有前辈知道是什么原因吗
第二种,如果时间步长的控制设置为稳定和收敛 Stability and convergence(默认)。则压力迭代次数大于时间步长减小前的最大迭代次数(最大迭代次数可通过 Model Setup > Numerics > Pressure iterations > Convergence Controls > Maximum number of iterations before time step is reduced 设置)会导致的时间步长会被减小。

cells, whereas stimulation with EGF resulted in logarithmic fold changes of about 1.5 at early time points in most cells. The logarithmic fold change for the second phase was clearly different between low and high doses of EGF (Figures 2C andS2B), as stimulation with, for example, 1 ng/...
“Time-step size < dtmin” 问题解析 实际运行中常遇到了 Time-step size < dtmin 的情况。 1. 发生的原因 求解器的停止是因为时间步长小于最小时间步长。这里涉及两个量,最小时间步长,时间步长。最小时间步长默认为 1e-4 乘以初始时间步长,其值也可通过
Existing computational methods that use single-cell RNA-sequencing (scRNA-seq) for cell fate prediction do not model how cells evolve stochastically and in physical time, nor can they predict how differentiation trajectories are altered by proposed inter
If the poke output is maintained on consecutive time steps, the cost is reduced to 10% of that for the first poke. In a rewarded trial, the reward (with value 1) is collected by the first ‘poke’ action after the reward delivery click. We adopted the convention4 that the reward ...
(1−NMIbatch)=1 implies no batch effect present after integration. Hyperparametermis the number of “ghost” cells, anddis the dimension of the reduced gene expression matrix. The bolded entries are the best performance metrics for each scenario. See the “Methods” section for details on ...
