Adaptive linear second-order energy stable schemes for time-fractional Allen-Cahn equation with volume constraint

•A volume-preserving time-fractional Allen-Cahn model is developed.•Adaptive linear second-order energy stable schemes are developed.•The proposed adaptive time-stepping algorithms are appropriate for accurately resolv- ing the initial singularity of solution and for efficiently capturing the fast d...
