摘要
我们为模仿 sine-Gordon 方程建立格子 Boltzmann 方法的一个含蓄的计划,它能被转变成明确的,因此计划的计算简单。而且,参数。含蓄的计划中独立于松驰时间,它使模型更灵活。数字结果证明这个方法是很有效的。
We establish an implicit scheme of lattice Boltzmann method for simulating the sine-Gordon equation, which can be transformed into the explicit one, so the computation of the scheme is simple. Moreover, the parameter θ of the implicit scheme is independent of the relaxation time, which makes the model more flexible. The numerical results show that this method is very effective.
